Apple Watch

Apple Watch is a line of smartwatches developed, designed, and marketed by Apple Inc. It incorporates fitness tracking and health-oriented capabilities with integration with iOS and other Apple products and services. The original generation of the device was available in four variants: Apple Watch Sport, Apple Watch, Apple Watch Hermès, and Apple Watch Edition; each distinguished by different combinations of cases and first- or third-party interchangeable bands. Apple Watch relies on a wirelessly connected iPhone to perform many of its default functions such as calling and texting. It is compatible with the iPhone 5 or later models running iOS 8.2 or later, through the use of Wi-Fi or Bluetooth. Announced by Apple CEO Tim Cook in September 2014, the device was released in April 24, 2015. The Apple Watch quickly became the best-selling wearable device with the supply of 4.2 million smartwatches in the second quarter of the 2015 fiscal year. The second generation of Apple Watch, released in September 2016, includes two tiers: Apple Watch Series 2 and Apple Watch Series 1, which includes the S1P chip, but is otherwise identical to the original.

The original Apple Watch comes in four collections (Apple Watch Sport, Apple Watch, Apple Watch Edition, and Apple Watch Hermès) and features two case sizes: 38 mm (1.5 in) and 42 mm (1.7 in). The

Luxury Gemstone

One of the most luxurious jewelry items that are produced are gemstone-encrusted timepieces. These range from affordable watches with a few small gemstones or mother-of-pearl inlay decorating the dial, to showcase timepieces that are completely covered in colored gems, with a “secret” dial that is hidden by a decorative feature. Some brands have their own signature style; for example, Graff Diamonds have a signature triangular gemstone on the faces of their classic watch collection. When it comes to men’s luxury watches, it is important to consider wrist size, function and budget. A man with a large wrist size should consider a chunky timepiece, where a man with a more slender wrist can wear a smaller watch. Some like to combine luxury with technology and others prefer classic workmanship. If the watch is to be worn daily, durability must be considered, and some leather straps may need to be replaced after being worn for some time. Men’s watches tend not to have gemstone-encrusted bands, unless you happen to be Jay Z, who received a specially commissioned “Hublot Big Bang” watch from his wife Beyoncé that contained over 1000 white diamonds. It is worth

Pink Gemstones

Pink and red diamonds are the among the rarest gems in the world. So let’s consider more achievable options. You’ll find interesting shades of pink in both sapphire and ruby. In fact sapphire and ruby are the same mineral – corundum, the second hardest gem material after diamond. Ruby is the name reserved for the red variety of corundum. A pink-red corundum is most often called ruby, while any other shade of pink corundum is usually called a sapphire. The Burmese pink-red rubies are quite famous and have a fabulous fluorescent quality. Pink sapphire occurs in colors from the lightest pink to fuchsia. It can be quite hard to find, but nice pieces are available from sources including Madagascar. The most popular pink stone among the finer gemstones must be tourmaline. You can find every possible shade of pink in tourmaline, including fascinating bi-color and tri-color pieces. If you’re searching for a hot pink gem, you’ll most likely find it in tourmaline. Also you’ll find soft pinks in every imaginable shade. Kunzite, the pink variety of the gemstone spodumene, was named after the famous American mineralogist, George Frederick Kunz. It is typically a very light-pink or

History Watch

Watches evolved from portable spring-driven clocks, which first appeared in 15th century Europe. Watches weren’t widely worn in pockets until the 17th century. One account says that the word “watch” came from the Old English word woecce which meant “watchman”, because it was used by town watchmen to keep track of their shifts at work. Another says that the term came from 17th century sailors, who used the new mechanisms to time the length of their shipboard watches (duty shifts). Drawing of one of his first balance springs, attached to a balance wheel, by Christiaan Huygens, published in his letter in the Journal des Sçavants of 25 February 1675. The application of the spiral balance spring (spiral hairspring) for watches ushered in a new era of accuracy for portable timekeepers, similar to that which the pendulum had introduced for clocks.

A great leap forward in accuracy occurred in 1657 with the addition of the balance spring to the balance wheel, an invention disputed both at the time and ever since between Robert Hooke and Christiaan Huygens. This innovation increased watches’ accuracy enormously, reducing error from perhaps several hours per day to perhaps 10 minutes per day, resulting in the addition of the minute hand to the face from around 1680 in Britain and 1700 in France. The increased accuracy of the balance wheel

Digital Watch

A digital display shows the time as a number, e.g., 12:08 instead of a short hand pointing towards the number 12 and a long hand 8/60 of the way round the dial. The digits are usually shown as a seven-segment display. The first digital mechanical pocket watches appeared in the late 19th century. In the 1920s, the first digital mechanical wristwatches appeared. The first digital electronic watch, a Pulsar LED prototype in 1970, was developed jointly by Hamilton Watch Company and Electro-Data, founded by George H. Thiess. John Bergey, the head of Hamilton’s Pulsar division, said that he was inspired to make a digital timepiece by the then-futuristic digital clock that Hamilton themselves made for the 1968 science fiction film 2001: A Space Odyssey. On 4 April 1972, the Pulsar was finally ready, made in 18-carat gold and sold for $2,100. It had a red light-emitting diode (LED) display.

An early LED watch that was rather problematic was The Black Watch made and sold by British company Sinclair Research in 1975. This was only sold for a few years, as production problems and returned (faulty) product forced the company to cease production. Most watches with LED displays required that the user press a button to see the time displayed for a few seconds, because LEDs used so

Huawei Watch

The Huawei Watch is an Android Wear-based smartwatch developed by Huawei. It was announced in 2015 Mobile World Congress on March 1, 2015, and was released at Internationale Funkausstellung Berlin on September 2, 2015. It is the first smartwatch of Huawei. The Huawei Watch’s form factor is based on the circular design of traditional watches, supporting a 42 mm (1.4 inch) AMOLED screen. The screen’s resolution is 400 x 400 pixels and 285.7 ppi. The case is 316L stainless steel, covered with sapphire crystal glass on front and available in six finishes: Black Leather, Steel Link Bracelet, Stainless Steel Mesh, Black-plated Link Bracelet, Alligator-pressed Brown Leather and Rose Gold-plated Link Bracelet. The watch uses 1.2 GHz Qualcomm Snapdragon 400 processor. All versions of the Huawei Watch have 512MB of RAM and 4GB of internal storage. It preloads gyroscope, accelerometer, vibration motor, and heart rate sensor. It supports WiFi and Bluetooth 4.1 LE, and no support for GPS locating. The watch uses a magnetic charging cradle, with a day and a half battery life. The watch pre-installed Android Wear operating system and it works with iOS (8.2 and later) and Android (4.3 and later) devices. It currently supports Google Now voice commands. The watch can process calls and receive messages and emails. In TechAdvisor ‘s review, Chris Martin wrote “this is a great looking smartwatch, although it

Analog Watch

Analog watches as well as clocks are often marketed showing a display time of approximately 1:50 or 10:10. This creates a visually pleasing smile-like face on upper half of the watch, in addition to enclosing the manufacturer’s name. Digital displays often show a time of 12:08, where the increase in the number of active segments or pixels gives a positive feeling. Traditionally, watches have displayed the time in analog form, with a numbered dial upon which are mounted at least a rotating hour hand and a longer, rotating minute hand. Many watches also incorporate a third hand that shows the current second of the current minute. Watches powered by quartz usually have a second hand that snaps every second to the next marker. Watches powered by a mechanical movement appears to have a gliding second hand, although it is actually not gliding; the hand merely moves in smaller steps, typically 1/5 of a second, corresponding to the beat (half period) of the balance wheel. In some escapements (for example the duplex escapement), the hand advances every two beats (full period) of the balance wheel, typically 1/2 second in those watches, or even every four beats (two periods, 1 second), in

Watch

A watch is a small timepiece intended to be carried or worn by a person. It is designed to keep working despite the motions caused by the person’s activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet. A pocket watch is designed for a person to carry in a pocket.

Watches evolved in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. In the 1960s the electronic quartz watch was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechanical watch.

Today most inexpensive and medium-priced watches, used mainly for timekeeping, have quartz movements. Modern watches often display the day, date, month and year, and electronic watches may have many other functions. Time-related features such as timers, chronographsand alarm functions are common. Some modern designs incorporate calculators, GPS and Bluetooth technology or have heart-rate monitoring capabilities. Some watches use radio clock technology to regularly correct the time. Developments in the 2010s include smartwatches, which are elaborate computer-like electronic devices designed to be worn on a wrist. They

Smartwatch

A smartwatch is a computerized wristwatch with functionality that goes beyond timekeeping. While early models can perform basic tasks, such as calculations, translations, and game-playing, 2010s smartwatches are effectively wearable computers. Many run mobile apps, using a mobile operating system. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, also called ‘watch phones’, feature full mobile phone capability, and can make or answer phone calls or text messages. While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED. Some use transflective or electronic paper, to consume less power. Most have a rechargeable battery and many have a touchscreen. Peripheral devices may include digital cameras, thermometers, accelerometers, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD card.

Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a heads-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies like Bluetooth, Wi-Fi, and GPS. For many purposes, a “wristwatch computer” serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health related applications.

“Sport watch” functionality often includes activity tracker features (also

Flower Gemstone Jewelry

Gemstone jewelry carvings have been made for thousands of years; since before faceting techniques were developed. Gemstones such as jade and carnelian were carved by the ancient Mesoamericans, Sumerians, Egyptians, Greeksand Romans. In ancient Egypt, scarab beetles and other animal forms were fashioned from gemstone material like turquoise, and used as amulets. One well-known ancient Egyptian ring is made from gold and features a carnelian carving of a cat. It is displayed in the British Museum. Contemporary floral motif jewelry has been blooming on catwalks all over the world in the past few years. These romantic pieces range in style from small, delicate flower carvings used as stud earrings and beaded necklaces accented by a single flower to large, bold statement necklaces surrounded by multicolored gemstones and chunky carved flower bracelets. Floral jewelry need not be old-fashioned and reserved for brooches; but can be updated with modern features, such as mixed metals and unusual settings. For example, carved gemstone flowers are ideal for stud earrings, as part of dangle earrings or as elements of charm bracelets.

In addition to jewelry, carved flower gems make pretty hair decorations. Gems can be added to pins, clips or hairbands for unique fashion accessories. These can be simple clips or elaborate statement headdresses like those seen at the 2015 Met

Titanium Jewelry

Titanium is known as an extremely strong silvery white metal. Its name comes from the mythical Greek Titans, who were giants of great strength. Its name was assigned by Martin Heinrich Klaproth after titanium was discovered in Cornwall (UK) in 1791 by William Gregor. However, titanium was not produced in a pure form until 1910 when Matthew A. Hunter invented a method to produce 99.9% titanium. One of the most famous titanium pieces is the exterior of the Guggenheim Museum in Bilbao, Spain, which is covered in sections of bright titanium. The whiteness of the compound titanium dioxide is useful in the production of white pigments. As well as being light in color, titanium is also very lightweight, which is surprising due to its incredible strength. Because of the combination of titanium’s light weight and superior strength, titanium alloys have become very useful in the aerospace industry and other spheres, including medicine and jewelry. Also, because titanium jewelry has such low density, it is one of the most comfortable metals when it comes to wearability.

One downside to titanium jewelry lasting for life is that it is so strong that it can be difficult to remove easily in the event of a medical emergency. This also means that it

Summer Jewelry Style

Summer is the time to cast off bulky clothing and emerge from our warm winter clothes. Springalso offers a chance to prepare for the heat of summer, with some lighter clothing and brighter colors. Once summer is in full swing, the jackets come off, feet come out of shoes and flesh is shown off. Colors that trend are bold hues or pretty pastels. Thus, summer fashions seem to go two ways; either cool or hot. The bright sunlight really enhances colors and the hotter weather opens up possibilities for many different jewelry styles that are not always possible in the freezing winter. Bright colors may be worn as clothing and complemented by toned-down jewelry colors or vice versa. Colors have an effect on mood, so using them to your advantage will get you into the lively summer spirit. White, cool blue and pale pink are always popular summer colors. There are several gem types to choose from that are white, from rock crystal (white quartz) and brilliant zircon to pearls. In pale blue, the most popular choices are aquamarine and topaz, but there are some other interesting gems in pale blue, such as Larimar. There are several romantic pastel pink gems, including tourmaline, rose quartz, kunzite, spinel, sapphire and

Gold Alloys

 In the jewelry industry, gem settings or mountings are known as ‘jewelry findings’, and when most people think of ‘findings’, gold is almost always the first material to come to mind. Gold’s stability makes it ideal for jewelry since it is one of the few noble metals that are resistant to oxidation and corrosion. Many consumers are often surprised to learn that pure gold settings are rarely seen in jewelry findings anymore. Today, almost all gold jewelry mountings are actually forms of ‘gold alloy’. An alloy can be any form of mixed metal compound; to be a gold alloy, it must contain at least one part gold combined with one or more other elements.

Gold is one of the most popular and traditional jewelry-making materials, but in its purest form, it is rather soft and therefore not ideal for most jewelrydesigns. For most of time, pure gold has been the standard and it still is in many Asian countries. But through innovation, jewelry trends have evolved – bringing about the introduction of various elements fused with gold or ‘gold alloys’. By far, the most popular gold alloy is ’18K’ gold. The karat, which is abbreviated to ‘K’ or ‘kt’ is the unit of measurement used in reference

Silver Gemstone Jewelry

Gold alloys can be made in many colors, bronze is in trend, and white metals, such as platinum and palladium are timeless. Silver alloys have been traditionally associated with flatware, coins and jewelry. Pure silver is typically too soft for jewelry use. In fact, like gold, silver can be hammered into ultra thin sheets. Thus, silver is alloyed to increase its strength and durability. Silver is an attractive bright white metal that can be highly polished. In fact, silver has the most brilliant polish of all the precious metals. The polish of silver can have a mirror finish or a satin look. This makes it a great metal for jewelry. Additionally, silver is relatively inexpensive. This means that a good collection of white metal gemstone jewelry can be accumulated without paying for white gold or platinum. Silver jewelry can be worn alongside white gold jewelry, since it matches in color. In fact, it can be difficult to tell the difference between the two.

Like gold, silver can be alloyed with other metals to increase its strength and durability. Sterling silver is an alloy that contains a minimum of 92.5% silver. It is usually alloyed with copper, which strengthens the silver while allowing it to be ductile. Other,

The Oldest Jewelry

The oldest known jewelry items are two shell beads that were found in Skhul Cave in Israel. The organic beads are around 100,000 years old and about the size of peas. They come from a type of marine mollusk called Nassarius and had been perforated, perhaps by tools made from flint, which led to the conclusion that they were used as beads. It is thought that the beads were not only decorative, but also served a symbolic purpose. A larger quantity of similar beads were also discovered at Blombos Cave in South Africa. The South African beads are around 70,000 years old and differ in that some held traces of red ochre. This suggests that these early beads may have been dyed and could be the very earliest known case of gemstone treatment. Alternatively, the beads could have rubbed against a dyed surface, such as skin that had been coated with red ochre.

Another Nassarius shell bead was also found at Oued Djebbana, Algeria. The bead is thought to be at least 35,000 years old. Since the location of the site where the bead was found was around 160 kilometers from the natural marine habitat of Nassarius, it was concluded that the bead was transported. These discoveries provide evidence

Multicolor Gems and Jewelry

There is always a place for timeless classics like white diamond solitaire rings, but colorful gemstones and jewelry brighten up a look and provide a little fun and contrast. With colored gemstones, there is a wealth of color to be appreciated and used in jewelry. Multicolored jewelry does not need to be cheap; indeed, a great deal of fine jewelry makes use of fancy colored gemstones and there are almost limitless color combination possibilities with colored gemstones. The use of color is an art in itself, and can be used to create contrast or harmony. Some of us consider color harmony and symmetry to be pleasing to the eye. Others like to experiment with contrast and asymmetry. There is no right or wrong with colored gemstone jewelry design, but what merely what feels right for each individual and makes them happy. Color fashions always come and go, especially when it comes to clothing and accessories; but color itself will never go out of fashion. The fashion industry thrives on color trends which change with the seasons. However most gemstone jewelry is designed to outlast such short-term fads.

Colored gemstones used to be set mainly into either white or yellow precious metal, but nowadays, it is possible to

Brown Gemstones

  • Brown Agate

Agate is a banded form of chalcedony quartz that occurs in many different colors and even geodes, which are rock cavities or vugs with internal crystal formations or concentric banding. Brown agate gemstones include fire agate, which is admired for its fiery iridescence; and dendritic agate; brown agate with black dendritic inclusions. Agate gems are extremely versatile and may be sold as beads, cabochons, faceted gems, agate geodes, carvings, slices or as tumbled stones. Agate geode gems and slices are particularly popular for their “raw” look. Jewelry made from agate is hard and durable enough to last for centuries, with a pleasing waxy luster and translucent to opaque clarity.

  • Brown Andalusite

Andalusite is a lesser-known gem that gets its name from Andalusia, where it was first found, though it is now found in many places, such as Australia, Russia, Canada, Brazil, Sri Lanka and the USA. It shares the same composition as sillimanite and kyanite (aluminum silicate), making all three minerals polymorphs; minerals with the same composition, but different crystal structures. Andalusite has strong pleochroism; the ability to exhibit different colors from different angles, which gives andalusite unique combinations of color.

  • Brown Axinite

Axinite is a rare, violet,

White Colorless Gems

When diamonds simply aren’t practical or cost-effective, what type of gem do jewelers seek out in regard to the most common white gem alternatives? When it comes to large white gems, the most affordable and available is white (colorless) quartz and white (colorless) topaz. Clean, faceted topaz and quartzgemstones can be found in very large sizes, often weighing in at 10 carats or more. Try finding a 10 carat diamond even remotely eye clean, or even affordable for that matter. White quartz, also known as rock crystal, is the defining mineral for 7 on Mohs scale of hardness, which means it is quite durable and is considered to be quite suitable for most jewelry designs, including rings. However, when used as a diamond substitute, white quartz definitely requires a brilliant or diamond-cut since it doesn’t have as much brilliance compared to other white gemstone types. It lacks the fire and dispersion of diamond and sapphire, but it offers excellent affordability and can be found in extremely large sizes. It is very common to find white quartz in oversized cocktail rings and fashion or ‘costume’ jewelry.

White topaz is slightly harder than quartz (8 on the Mohs scale) making it more resistant to scratches; but because of its perfect cleavage, it can easily

Purple Gemstones

Purple are both a mix of blue and red with some hues being nearer to blue and others closer to red. The terms “purple” are often used interchangeably, but there is a subtle difference. On a traditional color wheel, violet is next to blue and purple is between violet and red. This means that violet is a cooler hue than purple. Purple and violet have certain connotations; some of these are individuality, religion, royalty and wealth. In some spheres, purple is seen as a middle ground between aggressive red and tranquil blue. This is true in politics, where red and blue have particular affiliations and associations.

The first purple gemstone that usually springs to mind is amethyst, which is a variety of quartz and occurs as geode gems as well as polished stones. Fine amethyst has been mistaken for purple sapphire in the past, in particular, the Delhi Purple Sapphire, which has an interesting story of ill-fate. Yet, this beautiful purple gemstone actually turned out to be a rather large amethyst. Other well-known amethysts include the Duchess of Windsor’s amethyst and turquoise necklace designed by Cartier in 1947 and the Kent Amethyst Demi-Parure owned by the Queen of England. While deep purple amethyst is valued above all,

Black Metal Jewelry

Nowadays, metals for jewelry are becoming so varied that it is possible to wear almost any color metal jewelry, even multicolored titanium, which is electrolytically colored. Metals can either be plated or alloyed to create unique colors. For example, gold can be alloyed with white metals to produce white gold and rhodium plating produces a bright, white finish on jewelry. It is even possible to make blue and purple gold alloys to match colored gemstones.

A recent color trend for jewelry is black metal, which has an unconventional but pleasing look. Some gemstones look particularly dramatic when set into black metal. For example, the Boucheron Ivy Emerald Tiara worn by Queen Rania of Jordan is a stunning piece of work. The emeralds are set in black gold so that the metal takes a backseat and the bright green emeralds are showcased in the wreath design. There are several ways in which black metal jewelry can be achieved. For example, a black gold alloy can be made. Black gold alloys are typically made from 25% cobalt to 75% gold, though other alloys exist. Though these are referred to as “alloys”, the black color is only a surface layer. Black gold production usually involves controlling the oxidation process to produce
