Gemstones Used in Jewelry Making (Page 1)
The following is a partial listing of Faceted or Cabochon Gemstones available for use in Jewelry. This listing contains the standard gemstones used commonly in jewelry, plus Pearls , Opals, Coral and several synthetic and simulated man-made stones that have found their way into designer jewelry because of their beauty.
|
 |
 |
|
As the cost of some of the colored gemstones increases, the old concept of precious and semiprecious stones is slowly taking a backseat to the actual value of the individual gemstones. Today several of the colored gemstones are much rarer and cost much more than the Diamond. In addition to gold, silver, and platinum, Diamonds are still the most commonly used gemstone in jewelry, but some of the colored gemstones are rapidly becoming more popular and much more expensive. To stay in touch with both areas of thinking, here is a listing of what has been refered to as -------
Precious stones: Diamonds have traditionally been the most highly prized of these stones, varying in color from yellow to bluish white and sometimes reaching enormous size. Rubies, Emeralds, and Sapphires are also considered in this category, along with certain varieties of the less costly Chrysoberyl, Topaz, and Zircon.
|
 |
 |
|
Semiprecious stones: Amethyst, Garnet, Opal, Aquamarine, Jade , Turquoise, Agate, Onyx, Lapis Lazuli and Malachite. Also there are some gemstones that are of Organic Origin: Amber, a fossil tree resin, is a highly valued stone. Pearls and Corals, though animal in origin rather than mineral, are also usually considered gemstones.
|
 |
 |
|
Gemstones have attracted humans since ancient times, and have long been used for jewelry. Diamonds, especially, but also Rubies, Emeralds, Sapphires and in Ancient Egypt, Lapis Lazuli, were a sign of wealth and prosperity as well as beauty. The Royalty of Europe favored various colored gemstones, which has only increased their popularity today. The prime requisite for a gem is that it must be beautiful. The beauty may lie in color or lack of color. A gem must also be durable to withstand the wear and tear of constant handling and it must be available to the consumer.
Note that there are several listing that indicate the stone is new from Tucson GemFair 2008. These are either new stones presented for the first time at Tucson and/or varieties that have not previously been easily found and seen.

Alexandrite is the best known variety of chrysoberyl. It is known by most people as the stone that is ‘Emerald by Day and Ruby by Night’, because of its color change attributes. Alexandrite was discovered in 1831 in the Ural Mountains (Russia) on the Czar Alexander II’s birthday, and thusly named for him. Today it is very difficult to find a natural Alexandrite. Because of its rarity, most Alexandrite on the market is either a synthetic or simulate. However, a Russian Lab Synthetic Alexandrite is almost impossible to tell from a real stone.

|
Do you love both the purple of amethyst and the sunny gold of citrine? With ametrine, another member of the quartz family you can have both gem colors for the price of one! Ametrine is especially inexpensive when you consider that it comes from only one mine in the world, the Anahi Mine in Bolivia. When a Spanish conquistador received it as a dowry on marrying a princess named Anahi from the Ayoreos tribe, Ametrine was introduced to Europe It is not sure if this gemstone was named for the Princess or for the America’s, from where it came.

|
|
|
Andalusite
|


|
Andalusite is pleochroic, i.e. it shows different colors in different directions. In the past andalusite was sometimes called "poor man's alexandrite" because it offered a play of color at a low price, but in fact it does not actually bear much resemblance to alexandrite, because it is not a color-change stone at all, the colors are present at the same time. However, that should not diminish its appeal, especially for those who like earth tones. Andalusite is named after Andalusia, the province of Spain where it was first discover. A variety of Andalusite known as Chiastolite displays the famous Trapiche ‘Wagon Wheel’ phenomena, like in Trapiche Emeralds, Rubys, Sapphires and Tourmalines.

|
Andesine
? ? ? ? ? ?
|



|
Andesine is only a minor constituent in most granites and syenites, but is the dominant variety of feldspar in certain igneous rocks called, appropriately andesites. Andesine is a member of the Plagioclase Feldspar Group and by definition must contain 50-70% sodium to 30-50% calcium in the sodium/calcium position of the crystal structure. Faceted Andesine can only be differentiated from faceted Labarorite by specialized testing by sophisticated gemological labs.
|
With recent questions now being asked about Andesine, it is more of a What it is not, than what it is ! Some claim it is natural, some claim it is heat treated, some claim it is enhanced, and there is still confusion over where it comes from. The only thing probably for sure is that it is a member of the Plagioclase Feldspar Group. There is also a good chance that the yellow variety, known to come from Mexico and Canada, is probably another Feldspar variety called Bytownite. Of course one of the more known varieties of Labradorite is the “schiller” effect stone called ‘Sunstone’, where some of the best comes from Oregon.
|
|
Andradite
|

|
Andradite is a species of the Garnet Group. Andradite was named after the Brazilian mineralogist Jos Bonifcio de Andrade e Silva. It is found in Italy, the Ural Mountains of Russia, Arizona and California.

|
Apatite
|


|
Apatite has been infrequently used as a gemstone, however in recent years, due to the scarcity of Paraiba Tourmaline, it has become a highly prized substitute, especially for its ‘neon’ blue and green characteristics. Transparent stones of clean color are faceted, and chatoyant specimens, known as cat's-eye apatite, have been cabochon cut. The name "apatite" comes from the Greek word apate, which means "deceit" because it is easily confused with other minerals, especially paraiba tourmaline.
|
When worn is said to relieve arthritis and joint problems and reduce high blood pressure. Suppose to stimulate creativity and mental activity, bringing unconditional love while raising self-esteem.
|
|
Aquamarine
|


|
Aquamarine is the pale greenish blue or bluish green variety of beryl. Beryl has long been of interest because several of its varieties are valued as gemstones. These are aquamarine, emerald and heliodor. Aquamarine is the most common variety as it occurs in pegmatite formations, in which it forms much larger and clearer crystals than emerald. Aquamarine is sometimes confusing with almost clear or light blue Topaz, which is a much cheaper gemstone. Its name is derived from the Latin 'aqua' (water) and 'mare' (sea).

The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. It should not be confused with the natural stone zircon. Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important diamond simulant since 1976. Its main competition as a synthetic gemstone is the more recently cultivated material, synthetic moissanite. As its name implies, cubic zirconia is crystallographically isometric.
|
|
|
Danburite
|

|
Danburite is one of the few gemstones with a hardness of 10 on the Mohs Scale, but still not near that of a diamond due to the proportionality of the scale.

Diopside-Chrome
|


|
Chrome diopside certainly won't win any contests for the most beautiful name. To most people, it sounds more like a car polish than a gemstone. But don't be misled by that! Chrome diopside has a beautiful rich green colour and an amazingly low price. In fact it is the most affordable gemstone in a pure rich green. The drawback to Chrome diopside is that it is mostly available in small sizes. Since it is a single source from Siberia, it can only be mined about 3 months out of the year. It draws its name from the Greek dis - "two kinds" and opsis - "opinion."
|
Is suppose to assist those people who have experienced trauma in their life.

Emerald-Trapiche
|

|
Trapiche emeralds are in a class by themselves. Found only in Colombia at Coscuez, La Peña and the celebrated Muzo mining district, these are perhaps the rarest of "pattern" gems, and certainly the most unusual amongst the big three (emerald, ruby, and sapphire). Their six spoke-like carbon "rays" emanating from a hexagonal center with the areas in between filled with lively emerald green makes this a gem you'll never forget once you see one. These rays appear much like asterism, but, unlike asterism, they are not caused by light reflection from tiny parallel inclusions, but by black carbon impurities that happen to form in the same pattern. The name comes from the Spanish who when mining the gem called it trapiche from the word for gear wheel.

Goldstone - Sitara
|

|
Goldstone is a type of glass made with copper or copper salts in the presence of a reducing flame.The most common form of goldstone gives the illusion of being reddish-brown, although in fact that color comes from the copper crystals and the glass itself is colorless. Some goldstone variants have an intensely-colored glass matrix- usually blue or violet, more rarely green-- and a more silvery appearance to the suspended crystals. Curiously, goldstone is one of the few cases where a synthetic simulant provided the eponym for the similar natural stone. The original Italian name for goldstone is "avventurina" or some similar word or phrase indicating its accidental discovery. Do not confuse crystalized adventurine, also from the same Italian word, with manmade goldstone.
|
|
|
Heliodor or Golden Beryl
|

|
Golden beryl is one of the many hues of the "gemstone" mineral beryl. It can range in colors from pale yellow to a brilliant gold. Unlike emerald, golden beryl has very few flaws. The term "golden beryl" is sometimes synonymous with helidor, but in the strict sense, golden beryl refers to pure yellow or golden yellow shades, while Heliodor refers to the greenish-yellow shades. Helidor can be radioactive due to coloring element of uranium. Named after the Greek words for sun ‘helios’ and gift ‘doron’ because of its color..
|

|
Hematite
|

|
Hematites occur in opaque red or red-brown, until polished and then it becomes a silvery, shiny opaque stone that almost looks like metal. Hematite is heavy and relatively hard oxide mineral, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. The magnetic variety is known as Hematine. Hematite derives its name from the Greek word ‘haem’ (blood ) in allusion to its red color.

Suppose to fights hysteria. It strengthens the body while improves immunity and intuition.
|
|
Howlite
|



|
Howlite, which is named for its discoverer Henry How (a Nova Scotia geologist), is one of those minerals that is more famous for imitating another mineral. In this case the other mineral is Turquoise, a phosphate gemstone. Although Howlite is always white or gray, it can accept dyes fairly easily and can be dyed a turquoise blue. The look of Turquoise is so good that dishonest dealers have been unfortunately successful at this hoax. In more honest circumstances, dyed Howlite is an affordable substitute for turquoise carvings, beads, polished stones and cabochons. It accepts a nice polish and its porcelaneous luster is attractive and enhances even undyed beads and carvings. Also be aware, many try and sell the undyed Howlite as White Turquoise. Ivoryite/Magnesite is what the native American Indians from the southwest call White Buffalo Turquoise, but again it is not Turquoise. Cut and Tumbled Howlite, when dyed, has been sold as many different gemstone, so BUYER BEWARE. Most Howlite comes from California, but is now found in China also.
|
Howlite is a super-calming stone and many people use it to relieve stress of all kinds. It makes an excellent antidote to insomnia due to an overactive mind.
NOTE: pictures to the left show Blue and Green dyed Howlite which is passed off as Turquoise.

Idocrase
|

|
Idocrase forms as a result of contact metamorphism on impure limestones and is usually found with other exotic minerals. It is a somewhat rare and beautiful mineral that can rival many other minerals for interest among mineral collectors. Idocrase, also known as Vesuvianite, is a fascinating mineral found originally on the volcano, Mt Vesuvius, hence one of the names. Idocrase, is from the greek and means mixed form, an allusion to its crystals showing a mixture of other mineral forms.

|
|
Iolite
|

|
The transparent variety of iolite, it is often used as a gemstone. Gem quality iolite varies in color from sapphire blue to blue violet to yellowish gray to light blue as the light angle changes. Iolite was known as the Vikings' compass because of its ability to help determine the direction of the sun on overcast days. When the legendary Viking mariners sailed the ocean, they used thin pieces of Iolite as the world's first polarizing filter. Looking through an iolite lens they could determine the exact position of the sun and navigate safely. The name "iolite" comes from the Greek word for violet. Another old name is dichroite, a Greek word meaning "two-colored rock", a reference to cordierite's strong pleochroism. Iolite should not be confused with Tanzanite, for which it is many times called and sold in that manner.
|
Known to strengthens physical body, stimulates memory. Brings unconditional love and connection.
|
|
Ivoryite
|

|
Ivoryite is a great substitute for ivory. It is a sedimentary precipitate of magnesium, calcium and silica. It is around 5 on the Moh's scale, which makes it slightly harder than ivory. Ivoryite can be worked with metal tools, but cuts effortlessly with diamond tools. It polishes well with diamond, tin oxide, cerium oxide or white rouge. It is an excellent material for inlay, cabochons and small carvings. Some varieties of Magnesite are also called Ivoryite or White Buffalo Turquoise by native southwestern US Indians. Although found with Turquoise deposits in the SW United States, it is not White Turquoise.

Reflecting the azure blue waters of the Caribbean, Larimar is a recently discovered rare gemstone found in only one minesite on our Planet. Often mistaken for translucent Turquoise or fine blue Jade, Larimar beautifully mirrors the waters surrounding its island origin. Larimar's crystal vibrations and unique blend of colors have drawn many people to it. Scientifically, Larimar or Blue Pectolite is totally unique in it's mineral and chemical make-up. Copper, similar to what is in Turquoise, is the cause of the color. That is the only connection of Larimar to the ancient stone known as Turquoise. Sole sourced from the Island of Hispaniola in the Caribbean. Miguel Méndez and Peace Corps volunteer Norman Rilling discovered the stone in 1974. Miguel promptly took his young daughter’s name Larissa and the Spanish word for the sea “mar” and called the new find Larimar,

Marcasite
|

|
The two minerals, marcasite and pyrite, are often confused due to their similar characteristics. Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and, therefore, different symmetry and crystal shapes. The marcasite/pyrite polymorh pair is probably the most famous polymorph pair next to the diamond/graphite pair. Adding to the confusion between marcasite and pyrite is the use of the word marcasite as a jewelry trade name. The term is applied to small polished and faceted stones that are inlayed in sterling silver. But even though they are called marcasite, they are actually pyrite. Marcasite’s name is derived from the Arabic word for pyrite.

Moissanite
|

|
Moissanite, grown in laboratories, is now being cut as gemstones and is used as diamond simulants. Moissanite brings to the jeweler's table a similar index of refraction and better than twice the fire of diamond, but is only slightly less expensive due to the difficulty in growing the crystals. Moissanite is also a natural mineral that was first discovered in fragments of a meteorite in Diablo Canyon in Arizona. It was named in honor of its discoverer, Nobel Prize winner, Dr. Ferdinand Henri Moissan.

The total amount of Moldavite scattered around the world is estimated at 275 tons. There are now only four moldavite mines that are in full operation, all in the Czech Republic. Boldly attributing the material to a cosmic origin, Dr. F. E. Suess regarded moldavite as a special type of meteorite material for which he proposed the class name of tektite. The actual stone was named by A. Dufrnoy, Moldauthein, a small town in Bohemia, where it was first found.

This is a modification to the gemstone face that creates a highly polished, convex-cut, unfaceted gem that is smooth to the touch.
|
|
Portuguese 
|
The classic Portuguese (Vargas) cut has 161 facets on it. Because of the depth that is needed to cut that many tiers and facets the stone/design must be deep and thus caret weight is increased for the same diameter as a standard 58 facet design.

Please go to ‘Page 2’ for Gemstones O thru Z, and remember there are many more gemstones than have not been shown here, and the varieties of some of the gemstones, such as Agate and Jasper (Quartz), are almost unending, especially when it comes to tumbled stones, beads, chips and free forms. One thing to keep in mind is that there are standard sizes, especially when using faceted and cabochon stones. Also in many cases, the size of the gemstones, depending on the actual cutting, will also determine the carat weight, and thus play an important part in determining the gemstones value, whether it be a Diamond or a simple Quartz stone. And keep your eyes open, because what some people refer to as “tumbled rocks” or “rocks” might turn out to be a very rare and sought after gemstone.
