Tsavorite garnet, emerald and chrome tourmaline falls in the realm of green gemstones. Tsavorite garnet is very much similar to the clean green shadow of the bright green. On the other hand peridot and chrome tourmaline have an attractive yellowish green tinge.

Buying Gemstones

Before you purchase gems you must consider various things. For instance consider the sturdiness of gems. Not all gems are meant to be used for the same purpose. Studier ones and the lighter and more delicate ones can't be used for the same purpose. For instance burgundy is not as sturdy as ruby but can be effectively used in charms and rings. Tourmaline is not as durable as ruby, therefore should be used keeping this characteristic in mind. Delicate and soft stones like benitoite, tanzanite and iolite should be handled with greater care and are best suited for making pendants. Navy gemstones are best suited for trinkets and necklaces. Apart from the precious gemstones you can also avail of semi precious gemstones. If your funds are constrained you can opt for the semiprecious gemstones. These are easily available at your local jeweler's and you can use it to make rings. Though the semi precious stones are not as attractive as the precious gemstones, they are not exactly cheap looking either. Find an attractive one that suits your taste.

Garnets have been used in bracelets and brooches since the latter part of the 19th century. They have also been used as abrasives for materials such as glass, metal, plastic, wood, and leather due to their sharp fracture.

Tsavorite - A World-Class Gemstone

Whilst many gem-lovers have indulged themselves in the joy of owning Diamonds, Ruby, Emerald and Sapphires, many have not yet discovered equally rare and fine gems such as Tsavorite. Still relatively unknown to the gem-buying public, stones like Tsavorite present a unique and exciting opportunity as due to the fact they are little known, their prices are still relatively low compared with the "big 4". This will not always be the case as the charms of this beautiful gemstone is quickly becoming known to jewelers the world over who are marketing it to their clients creating a pull effect through the market which will eventually push up prices.

garnet earrings

Tsavorite is such exciting gem for a number of reasons. Firstly, it is a gemologically superior gemstone with very high brilliance, life, hardness, is extremely rare and most important, is very beautiful. In terms of its gemological properties: Its Refractive Index is very high at 1.74 (Ruby and Sapphire are 1.76) which means that it bends light to a high degree and as such, has excellent light return and hence brilliance. This is aided by its high Hardness on the Mohs scale (a rating of 7.5) which means it takes a good polish which leads to excellent luster. Its Dispersion Rating is double that of its green rival, Emerald, meaning that it is a much more firey gem. In terms of rarity, there is only 1 commercial source in the whole world - in East Africa.

GARNET

When looking to buy a Tsavorite, it is important you consider the 4C's just as if you were buying a Diamond. The first, and most important of these is Color. Obviously if the color is not fine, the stone will not be beautiful and it will lose its "raison d'etre". So look for a deep color saturation with a pure green (minimal yellow modifier is important-yellow is the bane of Tsavorite). The saturation of the color must be vivid. When buying online, this can be a confusing prospect as there are so many sellers all proclaiming their stones to be the finest and all the colors seem different. I suggest you use the resources at the bottom of this article to get a better idea of how color grades are constituted.

Second is Clarity. Many online sellers try to ignore or downplay this factor. The truth is that the majority of Tsavorite contains quite heavy inclusions and the majority of online sellers are peddling this material. The prices for Tsavorite that is moderately included is very different from those that are very slightly included or clean so keep this in mind. Fine stones should be almost loupeclean or loupeclean.

Thirdly, consider the quality of the cut, including symmetry, faceting and proportions. Fine stones are well proportioned, have proper facet junctions and good symmetry. The cut is instrumental in creating brilliance and badly cut stones lack brilliance and hence beauty to don't overlook this.

Carat Weight - this is the fourth "C" and is important with this gem type as Tsavorite does not come in large sizes generally speaking. The vast majority of Tsavorites are well below a carat and fine stones of 2 carats are considered very rare. This means that the per carat price increases quicker with Tsavorite than most stones as large Tsavorites as relatively so much rarer. A very fine 4 carat can retail as high as 00 per carat.

In summary, Tsavorite is a very exciting, beautiful gemstone with a bright future. Those gem enthusiasts that invest in a fine large piece now will be well placed to see the value of their investment rise in the near future as demand for the stone increases as consumers become more knowledgeable.

Garnet Gemstones come in a range of colors ranging from colorless to black, the only color they do not appear is blue. Garnet has a high specific gravity, which gives it a heavy weight. This makes it cost a little more than other Gemstones of the same size and carat weight. Garnet sand is also used for industrial purposes to make sandpaper and mixed with high-pressure water jets to cut steel. Many different Gemstones make up the Garnet Group, here is a list of the more well known.

GARNET

Pyrope...is the blood red variety of the group and was very popular in the 18th and 19th centuries, especially in 'Bohemian Jewelry'. The best stones have a fiery red color that does not darken too much after being set in Jewelry. Pyrope has a bright glassy look to it and gem quality stones are mined at Buell Park, beyond the reaches of the Painted Desert just east of Canyon de Chelly with specimens up to five carats not uncommon.

Almandite...ranges in color from deep red to violet-red and sometimes even black.

It's name is derived from a town in Asia Minor and it is often confused with Pyrope.

Often cut into cabochons with the underside hollowed out to allow more light to pass through the stone. Almandite can be brittle and have been known to chip while being faceted.

Rhodolite...has a beautiful bright purple-red color with it's composition between that of Pyrope and Almandite, it also has fewer inclusions. Rhodolite is regarded as a superior Gemstone to both it's red counterparts.

Spessartite...a rich orange to red-brown in color often with feather like inclusions, which are actually clouds of minute drops, clean Gemstone quality material is very rarely found and is often confused with Hessonite. A bright orange pure form of Spessartite, which is known as Mandarin Garnet is very rarely found in Gemstone quality material.

Hydrogrossular Garnet...has a very distinctive gooseberry-green color and is very often made into beads or cabochons. Very often inclusions of black magnetite are present which give the Gemstone a speckled look. Because of its resemblance to green Jade it is known as Transvaal Jade or Garnet Jade in South Africa. A variety of pink Hydrogrossular Garnet can also be found.

Grossular Garnet-Hessonite...A brown-orange to brown-yellow member of the Grossular Garnet group, Hessonite is also known as cinnamon stone. The Gemstone has inclusions of small crystals of apatite, that give a swirling effect.

Grossular Garnet-Tsavorite...is a lime-green to emerald-green member of the group, it was first mined in Kenya in 1968. Emerald-green crystals only produce small stones of 2 carats or less, ensuring that they are more expensive than the lime-green stones. Tsavorite is nearly always faceted as a Gemstone.

Demantoid...the bright green variety of andradite group of Garnet is very rare, it is also rare to find stones greater than 1 carat in weight. Demantoid has a very lively fire, as it has a higher light dispersion and brilliance than a diamond. The Gemstone has distinctive inclusions of yellow-brown hair like pieces of asbestos. Of all Garnets, Demantoid is by far the most valuable.

To give a gift of Garnet is believed to be a symbol of love and to show desire of a loved one's safe travel and speedy homecoming. Garnet Gemstones are said to help attract love and to assist in past life recall. Garnet Gemstones have been carried by travelers to protect them from accidents while far away from home.

This quite robust Gemstone is one of the few gems that look better in sterling silver rather than in gold. Above all enjoy the many different colors that Garnet Jewelry has to offer.
