The difference between Finnish spectrolite and other labradorites is that crystals of the former have considerably stronger and larger colourfulness, caused by its opaque base color; other labradorites have a transparent base color. The anorthosite-dominant plagioclase from Ylämaa, Finland was named by Walter Mikkola and then accepted as a commercial name by geology professor Aarne Laitakari, then director of Geological Survey of Finland. Spectrolite is often cut as a lapidary cabochon, similar to plain labradorite, to enhance the effect and is used as a gemstone.

Faceted blue apatite, Brazil Yellow colored apatites Apatite is infrequently used as a gemstone. Transparent stones of clean color have been faceted, and chatoyant specimens have been cabochon-cut. Chatoyant stones are known as cat's-eye apatite, transparent green stones are known as asparagus stone, and blue stones have been called moroxite.Streeter, Edwin W., Precious Stones and Gems 6th edition, George Bell and Sons, London, 1898, p306 If crystals of rutile have grown in the crystal of apatite, in the right light the cut stone displays a cat's-eye effect.

A cabochon of Lake Superior agate More than a billion years ago, the North American continent began to split apart along plate boundaries. Magma upwelled into iron-rich lava flows throughout the Midcontinent Rift System, including what is now the Minnesota Iron Range region. These flows are now exposed along the north and south shores of Lake Superior. The tectonic forces that attempted to pull the continent apart, and which left behind the lava flows, also created the Superior trough, a depressed region that became the basin of Lake Superior.

This technique is an ancient one and gemstones like this are described as being "en cabochon", which are still made to this day. The pearls and the stones were put into openings that were cut into the metal, and fastened with thin wires. The effect was that when the light shone in, the stones looked as if they would shine from within. The crown is decorated with 144 precious stones (including sapphires, emeralds and amethysts) (green and blue precious stones being proper to emperors in Byzantine imperial protocol) and about the same number of pearls.

P. Morgan in November 1900.

Star sapphire A star sapphire is a type of sapphire that exhibits a star-like phenomenon known as asterism; red stones are known as "star rubies". Star sapphires contain intersecting needle-like inclusions following the underlying crystal structure that causes the appearance of a six-rayed "star"-shaped pattern when viewed with a single overhead light source. The inclusion is often the mineral rutile, a mineral composed primarily of titanium dioxide. The stones are cut en cabochon, typically with the center of the star near the top of the dome.

Mosaics and ivories portray emperors, bishops, priests and the faithful wearing the hair of a medium length, cut squarely across the forehead. Women then wore a round head-dress which encircled the face. Emperors and empresses wore a large, low crown, wide at the top, ornamented with precious stones cut en cabochon, and jeweled pendants falling down to the shoulders, such as may be seen in the mosaics of S. Vitalis at Ravenna and a large number of diptychs. The hair of patriarchs and bishops was of medium length and was surmounted by a closed crown or a double tiara.

The pendants and beads all seem to have been strung together, probably forming a necklace that was in place around the neck of the body. Two of the pieces consist of gold cabochon pendants inset with jewels, while the third is a very elaborate shield-shaped jewel inlaid with 57 red garnets and a larger scallop-shaped gem in the centre. The garnets rest on a thin layer of gold leaf to reflect the light and increase their luminosity. It may have been created from recycled older pieces of jewellery, as the size, shape and thickness of the individuals garnet are all different.

A representative of the Smithsonian asked Paula Crevoshay, a jewelry designer from Albuquerque, New Mexico, to create a piece of finished jewelry from these gems. Crevoshay felt that a butterfly motif would best represent America's natural beauty, honor her mother's love of butterflies, and display the wide range of colors found in Montana sapphires. Crevoshay named the brooch "Conchita" in honor of her mother; it is also referred to as the "Sapphire Butterfly Brooch", "Conchita Sapphire Butterfly", and the "Montana Butterfly Brooch". Two of the sapphires used are cabochon cut and the rest are brilliant cut.

Lapidary clubs promote popular interest and education in lapidary, the craft of working, forming and finishing stone, minerals and gemstones. These clubs sponsor and provide means for their members to engage in all forms of jewellery making, cabochon cutting and faceting, carving, glass beadmaking and craft work. The clubs also promote and facilitate healthy outdoor activities in the form of field trips to various fossicking locations for the purpose of collecting gemstones or mineral specimens. Lapidary is particularly popular in the United States of America and Australia where large numbers of clubs were formed in the 1950s and 1960s.

While nephrite jade possesses mainly grays and greens (and occasionally yellows, browns or whites), jadeite jade, which is rarer, can also contain blacks, reds, pinks and violets. Nephrite jade is an ornamental stone used in carvings, beads, or cabochon cut gemstones. Nephrite is also the official state mineral of Wyoming. Nephrite can be found in a translucent white to very light yellow form which is known in China as mutton fat jade, in an opaque white to very light brown or gray which is known as chicken bone jade, as well as in a variety of green colors.

The Gemma Augustea is a Roman cameo produced 9–12 AD and carved in a two-layered onyx gem (19 × 23 cm) It has a long history of use for hardstone carving and jewelry, where it is usually cut as a cabochon or into beads. It has also been used for intaglio and hardstone cameo engraved gems, where the bands make the image contrast with the ground. Some onyx is natural but much of the material in commerce is produced by the staining of agate. Onyx was used in Egypt as early as the Second Dynasty to make bowls and other pottery items.

The egg was created by Faberge's workmaster, Mikhail Evlampievich Perkhin (Russian, 1860–1903) with miniatures by Johannes Zehngraf (Danish, 1857–1908) It stands about 248 mm (9 3/4 in) tall on its stand, with a diameter of 98 mm (3 7/8 in.) The outer shell is rock crystal banded with emerald-green enameled gold studded with diamonds. On the apex of the egg is a Siberian emerald supported by an emerald-green enameled gold mount. This cabochon-style emerald is one of the largest gemstones Fabergé used in any of the Imperial eggs.Lowes 2001, pg.

The gemstone at the front of the Imperial State Crown The Black Prince's Ruby is a large, irregular cabochon red spinel weighing set in the cross pattée above the Cullinan II diamond at the front of the Imperial State Crown of the United Kingdom. The spinel is one of the oldest parts of the Crown Jewels of the United Kingdom, with a history dating back to the middle of the 14th century. It has been in the possession of England's rulers since it was given in 1367 to its namesake, Edward of Woodstock (the "Black Prince").

The effect refers to the sharp milky ray of white light normally crossing the cabochon as a center line along its length and overlying the honey-colored background. The honey color is considered to be top-grade by many gemologists but the lemon yellow colors are also popular and attractive. Cat's eye material is found as a small percentage of the overall chrysoberyl production wherever chrysoberyl is found. Cat's eye became significantly more popular by the end of the 19th century when the Duke of Connaught gave a ring with a cat's eye as an engagement token; this was sufficient to make the stone more popular and increase its value greatly.

She also added a cap of purple satin, embroidered in gold and set with more diamonds, to the inside of the crown. The circlet of the crown has eight large cabochon rubies set beneath each of the eight arches of the crown and diamonds in large rosette patterns in the intervening spaces of the circlet. Queen Christina's crown was the crown chosen to be displayed with other items of the Swedish regalia and artifacts from the Swedish royal collections in a 1988-1989 exhibition at the National Gallery of Art in Washington D.C. and the Minneapolis Institute of Art commemorating the founding of Delaware as a Swedish colony in 1638.

Diamond held in its setting with a bezel In making a typical modern bezel setting, the bezel is shaped into the size and shape of the gem and then soldered into place on the metal of the jewelry. The prepared stone is then placed into the bezel and the metal is pressed down over the edges of stone, locking it into place. A cabochon stone, a gemstone that is not faceted, usually relies on the shallow angle cut into the side of the stone, which helps the metal to stay in place. With a clear faceted stone, such as a diamond, a shallow groove is cut into the bezel itself.

Lampwork Glass Eye Cabochon Tutorial Boro Lampwork glass beads Lampworking is a type of glasswork where a torch or lamp is primarily used to melt the glass. Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. It is also known as flameworking or torchworking, as the modern practice no longer uses oil-fueled lamps. Although lack of a precise definition for lampworking makes it difficult to determine when this technique was first developed, the earliest verifiable lampworked glass is probably a collection of beads thought to date to the fifth century BC.Lierke, Rosemary, "Early History of Lampwork – Some Facts, Findings, and Theories," Glastech.Ber.

As Elyse Zorn Karlin suggests, "The result was jewels of staggering beauty and imagination, sensual, sexual and beguiling, and at times even frightening. These jewels were a far cry from the symmetrical and somewhat placid designs of Arts and Crafts jewelry, which more closely resembled Renaissance jewels."Karlin, p 91 Lalique and other art nouveau jewelers quite often mixed precious metals and gemstones with inexpensive materials, and favored plique- a-jour and cabochon enamel techniques. Other important centers of art jewelry production included the Wiener Werkstatte in Vienna, where the architects Josef Hoffmann and Koloman Moser designed jewelry in silver and semi-precious stones, sometimes to be worn with clothing also created by the workshop.

A faceted shape resembles that of the modern diamond. It has a flat, polished surface, and it usually has a transparent surface that refracts light inside the gemstone and reflects light on the outside. In the case of a cabochon stone, the side of the stone is usually cut at a shallow angle, so that when the bezel is pushed over the stone that angle permits it to hold the stone in place and keep it tight. In the case of faceted stones a shallow groove is cut into the side of the bezel into which the girdle of the stone is placed, and then metal is pushed over, holding the stone in place.

Cabochons can also be set into prong settings of various kinds, but the idea is the same—it is the prongs going over the angle of the stone that creates the pressure that holds the stone in place. Just as the angle of the sides of a cabochon creates the pressure to hold the stone in place, so there is an overlying principle in setting faceted stones. If one looks at a side view of a round diamond, for example, one will see that there is an outer edge, called the girdle, and the top angles up from there, and the bottom angles down from there. Faceted stones are set by "pinching" that angle with metal.

Wristwatches and antique pocket watches are often appreciated as jewelry or as collectible works of art rather than just as timepieces. This has created several different markets for wristwatches, ranging from very inexpensive but accurate watches (intended for no other purpose than telling the correct time) to extremely expensive watches that serve mainly as personal adornment or as examples of high achievement in miniaturization and precision mechanical engineering. Traditionally, dress watches appropriate for informal (business), semi-formal, and formal attire are gold, thin, simple, and plain, but increasingly rugged, complicated, or sports watches are considered by some to be acceptable for such attire. Some dress watches have a cabochon on the crown or faceted gemstones on the face, bezel, or bracelet.

He was by the winner and good sire, Rego (IRE), his dam was the good broodmare, Dark Jewel by the outstanding sire, Star Kingdom (IRE) (pictured).du Bourg, Ross, The Australian and New Zealand Thoroughbred, Thomas Nelson, Melbourne, 1980, Dark Jewel produced 10 named foals for five stakes winners including Baguette’s full sisters, Birthright (won VRC Maribyrnong Plate) and Heirloom (won VRC Maribyrnong Plate, dead-heated for first in VATC One Thousand Guineas). Baguette was a half-brother to the stakes winners, Betelgeuse by Wilkes (FR) (City Tattersalls Club Lightning Stakes and AJC The Shorts) and Cabochon by Edmundo (AJC Epsom Handicap, QTC Stradbroke Handicap etc.) Dark Jewel’s progeny won over sixty-eight races for A$428,547 in prize- money in Australia and Malaysia.

Occasionally, twelve-rayed stars are found, typically because two different sets of inclusions are found within the same stone, such as a combination of fine needles of rutile with small platelets of hematite; the first results in a whitish star and the second results in a golden-colored star. During crystallization, the two types of inclusions become preferentially oriented in different directions within the crystal, thereby forming two six-rayed stars that are superimposed upon each other to form a twelve-rayed star. Misshapen stars or 12-rayed stars may also form as a result of twinning. The inclusions can alternatively produce a "cat's eye" effect if the girdle plane of the cabochon is oriented parallel to the crystal's c-axis rather than perpendicular to it.

Its lines and proportions are similar to those of tanks found on First World War battlefields; it is both a square and a rectangle, and its strap is seamlessly integrated into vertical sidebars called "brancards". Since its inception, variations of the watch have been released by Cartier, including the Tank Louis in 1922, the Tank Americaine in 1989, and the Tank Francaise in 1996. The defining features of a tank watch include its bold Roman numeral dial with a chemin de fer chapter ring, sword-shaped blued steel hands, and a sapphire cabochon surmounted crown. The Tank has become one of the most highly coveted and copied wristwatches of all time, and has been worn by Jackie Kennedy, Princess Diana, and Yves Saint Laurent, amongst many others.

The Star of Asia, a large, 330-carat cabochon- cut star sapphire in the U.S. National Gem Collection The Hope Diamond The National Gem and Mineral Collection is one of the most significant collections of its kind in the world. The collection includes some of the most famous pieces of gems and minerals including the Hope Diamond and the Star of Asia Sapphire, one of the largest sapphires in the world. There are currently over 15,000 individual gems in the collection, as well as 350,000 minerals and 300,000 samples of rock and ore specimens. Additionally, the Smithsonian's National Gem and Mineral Collection houses approximately 45,000 meteorite speciments, including examples of every known type of meteorite, and is considered to be one of the most comprehensive collections of its kind in the world.

The DeLong Star Ruby, a oval cabochon star ruby, was discovered in Burma in the 1930s. It was sold by Martin Ehrmann to Edith Haggin DeLong for , who then donated it to the American Museum of Natural History in New York City in 1937. On October 29, 1964, the DeLong star ruby was one of a number of precious gems stolen in a notorious jewelry heist by Jack Roland Murphy and two accomplices. In January 1965, nine of the stolen gems, including the Star of India and the Midnight Star, were recovered in a bus depot locker; however, the DeLong ruby was not among them.David Sears, "How Three Amateur Jewel Thieves Made Off With New York’s Most Precious Gems," Smithsonian, February 25, 2014. After months of negotiation, the unknown holder of the ruby agreed, through third parties including Dick Pearson, to ransom it for $25,000.

His opponents were the French horse Bog Frog (winner of the Prix Leon Rambaud and third in the Grande Course de Haies d'Auteuil), Top Spin (Winter Novices' Hurdle), Cabochon (Ascot Stakes) and Allegan (runner-up in the Yorkshire Cup). Cyborgo led from the start, went clear of his rivals approaching the penultimate flight of hurdles, and won by fifteen lengths from Top Spin, to whom he was conceding fourteen pounds. On 16 March 1995, Cyborgo made his first appearance at the Cheltenham Festival and started 3/1 second favourite behind the Irish six-year-old Dorans Pride for the 24th running of the three-mile Stayers' Hurdle, with the other contenders including Hebridean (Long Walk Hurdle), Bokaro (Corsa Siepi di Milano), Simpson (Premier Long Distance Hurdle) and Halkpous (Fighting Fifth Hurdle). Cyborgo led for most of the way before being overtaken two hurdles out and finished second of the eleven runners, three lengths behind Dorans Pride.

The vessel combines features of both a wasp nest and a honeycomb, natural forms that Betteridge studied in detail as part of her design process. A tiny, chased and repousséed bee in the recessed lid, and a golden quartz cabochon set in the handle of the stirrer, make droll references to the vessel’s use. This more interpretive phase of Betteridge's work found its most public expression in the late 1970s in two significant exhibitions: "Métiers d’art/3", which traveled to Canadian Cultural Centers throughout Europe in 1978-1979, and "Reflections in Gold and Silver", a major cross-Canada exhibition occasioned by her receiving the 1978 Saidye Bronfman award. In the 1980s, Betteridge undertook a new series of vessels composed of spherical, columnar and conical forms, fabricated in silver sheet combined with brass, copper, plexiglass, and rubber. The influence of Post-Modernism can be read in the juxtaposition of these formal geometric compositions with Betteridge’s characteristic wit, and in the mixing of precious metal with non- precious materials. For example, Mad Hatter’s Tea Party, 1988, is a teapot that combines a formal, globular body with base and handle elements of acrylic, silver and brass sheet.
