Translucent to opaque varieties

Blue Tourmaline Earrings

- Rhodochrosite

Jewelry Article: Colorful Choices in Colored Gemstones; Transparent Varieties Ii

Rhodochrosite is a new comer to the jewelry business. While sought by rock hounds for many years and a popular of starting lapidaries, rhodochrosite appeared only occasionally surface of rock and mineral shows frequented by hobbyists. A member of the carbonate mineral group, rhodochrosite is a relatively soft stone occurring in both a rare transparent and a more tasteless non-translucent variety. For practical purposes, we will discuss the latter, more easily available form.

A lovely red to approximately white color, often with agate like curved lines creating a form in contrasting shades of red or pink, rhodochrosite may occasionally occur in an orangy tone, but this is is poorer quality material. The finest color is a medium to deep rose, preferably with curved banding. It has long been popular for unavoidable decorative objects (spheres, boxes, eggs) but only recently for jewelry. Today, necklaces using rhodochrosite beads alternating with other gemstones or gold beads are becoming particularly popular. It is soft, however, and some caution should be used in wearing to avoid unnecessary abuse.

- Scapplite

Scapplite is an challenging gem that is starting to appear in more jewelry as it becomes more available. Rediscover in Brazil after a forty years hiatus and also recently discovered in Kenya, scapolite is a nice, transparent, fairly durable gemstone occurring in a range of colors from colorless to yellow, light red, orange to greenish to bluish gray, violet, and violet blue. The orange, light red, and whitish specimens may also occur as semitransparent stones, which may show a cat's eye consequent (chatoyancy) when cut into cabochons.

The most likely to appear in jewelry are the violets and yellows, and perhaps orange cat's eye. They might no ifs ands or buts be mistaken for yellow beryl or unavoidable quartz minerals like amethyst or citrine.

Consumers and sellers will have to wait and see what trends evolve nearby this gemstone, as its availability will settle future use and cost.

- Serpentine

Serpentine derives its name from its similarity to the green, speckled skin of the serpent. Amulets of serpentine were worn for security from serpent bites, stings of poisonous reptiles, and poison in general. A king was reputed to have insisted that his chalice be made of serpentine, as it was believed that a poisoned drink were put into a serpentine vessel, the vessel would sweat on the outside. The effectiveness of treatment was increased when drunk from a serpentine vessel.

Serpentine is often used as a jade substitute. It is a penetrative to semi-translucent stone occurring in light to dark yellowish green to greenish yellow. One variety is used for decorative wall facings and table counter surfaces, but some of the more challenging green varieties so closely look as if jadeite or nephrite jade that they are used in carvings and jewelry, and are often misrepresented as jade. tasteless serpentine is also sometimes dyed a jade like color. One lovely green variety, williamsite, which is a very pleasing deep green, often with small black flecks within, is often sold as "Pennsylvania Jade." It is pretty, but it is not jade. other variety of serpentine, bowenite, is also sold today as "Korean jade" or "new jade." Again, it is pretty but nit jade. Serpentine is softer than jade; less durable, and much more common, which its price should reflect.

It is a lovely gemstone in its own right, and makes a nice alternative to jade. While it has been nearby for a long time (too often, however, represented as jade), we are just starting to see this stone used oftentimes in necklaces and other fine jewelry under its own name.

- Sodalite

This gemstone has already been discussed under lapis. Sodalite is a dark blue semitransparent to semi-translucent stone used oftentimes as a substitute for the rarer, more costly lapis. While it may have some white veining, it does not have the golden or silver flecks that are characteristics of lapis. If you do not see these shiny flecks, think that the stone is probably sodalite.

- Spinel

Spinel is one of the loveliest of the gems but hasn't yet been given due prestige and respect. It is usually compared to sapphire or ruby, rather than being recognized for its own intrinsic beauty and value. There is also a tasteless reliance that spinel (and similarly zircon) is artificial rather than natural, when in fact it is one of the nature's most gorgeous products. This misconception probably arose because artificial spinel is seen oftentimes on the shop whereas genuine spinel is not often seen.
Spinel occurs in red orange (flame spinel), light to dark orangy red, light to dark slightly grayish blue, greenish blue, grayish green, and dark to light purple to violet. It also occurs in yellow and in an opaque variety; black. When compared to the blue of sapphire or red of ruby the color is usually determined less intense (although some red spinel can look very much like some ruby on the market), yet its brilliance can be greater. If you appreciate these spinel colors for themselves, they are quite pleasing. The most popular are red (usually a more orange red than ruby red) and blue (sometimes resembling a strong Bromo-Seltzer-bottle blue).

Spinel may be confused with or misrepresented as one of many gemstones; ruby, sapphire, zircon, amethyst, garnet, artificial ruby and sapphire or artificial spinel, as well as glass. The artificial is often used to make composite stones such as doublets. Spinel is a fairly hard, fairly durable gemstone, possessing a nice brilliance, and still a good value.

This gemstone is becoming more and more popular, and may, therefore, come to be more costly if current trends continue.

- Spodumene (Kunzite and Hiddenite)

Spodumene is other gem relatively new to widespread jewelry use. The most popular varieties are kunzite and hiddenite.

Kunzite is a very lovely fantastic gemstone occurring in delicate lilac, pinkish, or violet shades. Its color can fade in strong light, and so it has come to be known as an "evening" gemstone. Also, while basically hard, it is nonetheless brittle and can break no ifs ands or buts if it receives a sharp blow from unavoidable directions. It is not recommended for rings for this think unless set in a protective mounting. But it is a lovely gem, whose low cost makes it challenging in large sizes, and an exquisite choice for lovely, dramatic jewelry design.

Hiddenite is rarer. Light green or yellow green varieties are available, but the emerald green varieties are scarce. As with kunzite, it is hard but brittle, so care must be exercised in wear.

Spodumene also occurs in many other shades of colors, all pale but very clear and brilliant. Only blue is currently missing but who knows what may yet be discovered in some part of the world? Spodumene is still fairly inexpensive and is an exquisite choice for modern jewelry design. Be careful, however, as it can be confused with and sold for more costly topaz, tourmaline, spinel, or beryl. Also, artificial corundum or spinel can be mistaken for this gem.

- Sugilite

Sugilite named for the Japanese petrologist who discovered it, Ken-ichi Sugi, sugilite first appeared on jewelry scene in the late 1970s, sold as Royal Azel and Royal Lavulite. Best known today as sugilite, its lovely, deep rich purple to purple red color is unique. An opaque gem, it is usually cut in cabochon or beads, although it is also popular for inlay work (intarsia) by top artisans. Sugilite belongs to the manganese family and most comes from Africa. The finest color is already becoming scarce, so it is difficult to predict the future for this challenging newcomer.

- Tanzanite

See Zoisite below.

- Titanite (Sphene)

Titanite is other "new" gem that is starting to appear and offers some challenging possibilities for jewelry market. While it has been highly regarded for many years, its relative scarcity prevented its wide scale use in jewelry. Today, however, new sources have been discovered and we are starting to see greater availability.

This is a beautiful, fantastic gemstone, with a solitaire like (adamantine) luster and fire that is even greater than in diamond. Unfortunately, it is soft. Its colors range from grass green to golden yellow to brown.
There is need for some caution because of this stone's softness. We suggest that it is especially favorable for pendants, earrings, brooches, and protective ring settings.

- Topaz

True topaz, sticker of love and affection, aid to sweetness of disposition, and birthstone for November, is one of nature's most wonderful and least known families. The true topaz is rarely seen in jewelry stores. Unfortunately, most people know only the quartz (citrine) topaz, or glass, and in the past approximately any yellow gemstone was called topaz. A very gorgeous and versatile gemstone, topaz is a hard fantastic stone with a fine color range, and it is much rarer and much more costly than gemstones ordinarily sold as topaz. It is also heavier than its imitators.
Topaz occurs not only in the transparent yellow, yellow brown, orangy brown, and pinky brown colors most popularly linked with it, but also in a very light to medium red now found simply in fair supply, although many are produced straight through heat treatment. It is also found in a very light to medium deep blue, also often the consequent of treatment, although it does occur simply on a fairly wide scale. Other topaz shades include very light green, light greenish yellow, violet, and colorless.
Blue topaz has come to be very popular in new years, most of it treated; unfortunately, there is no way yet to settle which have been treated and which are natural. The blue form closely resembles the finest aquamarine, which is very costly today, and offers a very attractive, and much more affordable, alternative to it. Some of the fine, deeper blue treated topazes have been found to be radioactive and, agreeing to the Nuclear Regulatory Commission, may be injurious to the wearer. In the United States all blue topaz must be tested for radiation levels; the Gia now provides this assistance to the jewelry trade. However, be very truthful when buying blue topaz surface the United States. If you do, you may be wise to have it tested when you get home.

There are many misleading names to suggest that a stone is topaz when it is not, for example, "Rio topaz," "Madeira topaz," "Spanish topaz," and "Palmeira topaz." They are types of citrine (quartz) and should be represented as such.

The true topaz family offers a variety of color options in lovely, clear, brilliant, and durable gemstones. This family should come to be more foremost in the years ahead.

- Tourmaline

Tourmaline is a gem of modern times, but nonetheless has found its way to the list of birthstones, becoming an "alternate birthstone" for October. perhaps this honor consequent from tourmaline's versatility and broad color range. Or perhaps from the fact that red and green tourmaline, in which red and green occur side by side in the same gemstone, is reminiscent of turning of October leaves.

Whatever the case, tourmaline is one of the most versatile of gem families. It is available in every color, in every tone, from deep to pastel and even with two or more colors appearing in the same stone, side by side. There are bicolor tourmaline (half red and the other half green, for example) and tricolor (one-third blue, one-third green, and one-third yet other color). The challenging "watermelon" tourmaline looks like the inside of a watermelon; red in the center surrounded by green "rind." Tourmaline can also be found in a cat's eye variety.

One of the most challenging gemological discoveries of this century was the discovery of a unique variety of tourmaline in Paraiba, Brazil. These singular beauties, referred to as "Paraiba" or "Hetorita" after the man who discovered them, have colors so intense and come in such a wide range of green, blue, and lilac shades that they are referred to as neon tourmalines. Unfortunately, request has been unprecedented for these singular tourmalines, and furnish has dwindled. The consequent is that many of the finest Paraibas are very costly and some rival the finest sapphires in price. For whatever who loves these colors, they are worth looking just for their own sake. If jewelers in your area don't have these gemstones, they can sense the American Gem Trade connection in Dallas, Texas, regarding where to acquire them.

It is no ifs ands or buts surprising that most people know of tourmaline simply as a tasteless "green" gemstone. Nothing could be more misleading. Today, we are ultimately starting to see other lovely varieties of this challenging gem in the jewelry market. In expanding to the challenging new "Paraiba," other popular varieties include:

1) Chrome: A particularly rare green hue.

2) Indicolite: Deep indigo blue, usually with a green undertone.

3) Rubellite: Deep pink to red, as in ruby.

Tourmaline is a fairly hard, durable, brilliant, and very wearable gemstone with a wide choice of colors. It is also still available in large sizes. It is a gemstone without request will play a more and more foremost role in jewelry in the years ahead.

- Turquoise

Turquoise birthstone for December, and ranking highest among all the opaque stones, turquoise; the "Turkish gemstone," is highly prized throughout Asia Africa, not only for its singular hue of blue (a gorgeous robin's egg or sky blue) but more foremost for its supposed prophylactic and therapeutic qualities. The Arabs think it a lucky stone and have great reliance in its benevolent action. Used in rings, earrings, necklaces, head ornaments, and amulets, it protects the wearer from poison, reptile bites, eye diseases, and the evil eye. It was also believed capable of warning of impending death by changing color. Also, the drinking of water in which turquoise has been dipped or washed was believed to cure bladder ailments. Buddhists revere the turquoise because it is linked with a legend in which a turquoise enabled Buddha to destroy a monster. Even today it is determined a sticker of courage, success, and love. It has also long been linked with American Indian jewelry and art.

Turquoise is an opaque, light to dark blue or blue green stone. The finest color is an intense blue, with poorer qualities tending toward yellowish green. The preponderant Persian turquoise, which can be very intense and pleasing blue, is determined a very rare and significant gem.

All turquoises are susceptible to aging an may turn greenish or perhaps darker with gem. Also, care must be taken when wearing, both to avoid sense with soap, grease, or other materials that might discolor it, and to protect it from abuse, since turquoise scratches easily.

But rehearsal caution when buying turquoise. This is a oftentimes simulated gem. Very fine glass imitations are produced that are difficult to distinguish from genuine. Very fine adulterated stones, and reconstructed stones (from turquoise powder bonded in plastic) saturate the marketplace, as does artificial turquoise. There are techniques to speedily distinguish these imitations or simulations, so, if in doubt, check it out (and get a perfect record on the bill of sale; "genuine, natural turquoise").

- Zircon

Zircon is known to the ancients as "hyacinth," this gem had many powers, especially for men. While it was known to help women in childbirth, for men it kept evil spirits and drams away, gave security against "fascination" and lightning, strengthened their bodies, fortified their hearts, restored appetite, suppressed fat, produced sleep, and banished grief and sadness form the mind.

Zircons are very fantastic transparent gemstones available in several lovely colors. Unfortunately, many consumers suffer from a strange misconception that zircon is a artificial or artificial gemstone rather than a lovely natural creation. perhaps this reliance is based on the fact that they are oftentimes color treated, as in the blue zircons so often seen. Zircons also occur simply in yellow, brown, orange, and red.

Many might mistake the colorless zircon foe solitaire because of its strong brilliance, which coupled with its very low cost, makes colorless zircon an challenging alternative to diamonds as a gemstone to offset or dress up colored gemstones. But care needs to be exercised because zircon is brittle and will chip or abrade easily. For this reason, zircon is recommended for earrings, pendants, brooches, or rings with protective setting.

- Zoisite (Tanzanite)

Zoisite was not determined a gem material until 1967, when a gorgeous rich, blue to purple blue, transparent variety was found in Tanzania (hence tanzanite). Tanzanite can possess a rich, sapphire blue color, perhaps with some violet red or greenish yellow flashes. A gem green variety has recently been discovered, which is being called "green tanzanite"or "chrome tanzanite." The green can be a very lovely shade, ranging from a slightly yellowish green to gray green to bluish green. furnish is limited, so time will tell whether or not this green variety will be easily available to the public.

But one must be cautious. It is relatively soft, so we do not suggest tanzanite for rings (unless it's set in a very protected setting) or for every day wear in which it would be exposed to knocks and other abuse.
