Spectacular color tanzanite
Spectacular and beautiful are two words that describe the deep blue target = "_blank" title = "Loose Tanzanite"> tanzanite. The color varies from light blue to blue-violet. The most sought after blue tanzanite is a bright violet hue around it, which is extremely exciting in sizes above ten carats. Today, people pay almost any price for Tanzanite in particular good qualities larger sizes. After all, the charm to become the first owners of a rare beauty is certainly a factor in determining the value of this special gemstone.
It has better fire that many gemstones like peridot, tourmaline, tanzanite etc. creates the appearance of several colors in one stone: depending perspective, the stone appears blue, purple or yellow. Your one direction of cleavage is somewhat of a problem as it is oriented to the direction of more strong pleochroism. It is difficult for gemcutters to decide how the stone had to be cut. A problem in most gemstones, but with tanzanite the color is usually strong enough anyway.
Pleochroism is very pronounced in tanzanite and is seen as three different shades in the same stone. The Jewel is strongly trichroic. It might appear purple from one angle, blue from the second, yellow and brown of the third angle. Most crystals Raw show a large proportion of brownish-yellow, which is cured by carefully heating the stone in an oven at 500 ° C. heating demand maximum concentration because it is essential to determine the time when the color turns blue. Tanzanite warming is therefore a treatment that is accepted in trade, however, the stone must be as free of inclusions as possible, because otherwise the process can lead to cracks.
Working with Tanzanite is a careful task, even for experience cutters as the cutting of the gemstone is very high in one direction. It can be cut into any shape and form imaginable, classical to cutting round cuts imaginative design.
Tanzanite symbolizes trust and courage with unusual elegance. That such a gemstone purchases only difference of the masses and create your own style statement. The color of a mystic is not perfectly Tanzanite cut only appeals to young women, but women love to mature.

Green Fine Stones: Chrome Diopside
Looking for a green gemstone with fine rich and excellent clarity? What are your options? The option Emerald is traditional, but emerald is most famous for his color clarity. Tsavorite Garnet hit the market in the 1970s and, with the help of Tiffany & Co., became the second option, in fine, green gems. High quality tsavorite was not only an excellent green color saturation, had superior brightness, clarity and hardness. The only problem is that tsavorite became so popular that prices were as high or higher than emerald.
The next option was a rare variety of tourmaline green tourmaline known as chromium. As with tsavorite garnet, chrome tourmaline is found in eastern Africa, and colored by traces of chromium and vanadium. And as tsavorite, tourmaline fine chromium green forest is a pure visual in a slightly yellowish blue secondary. But chrome tourmaline was so scarce and expensive as tsavorite garnet.
The gems were just regular Green Left Peridot and green tourmaline. Peridot tended to yellowish or olive green, and never had the deepest voice of tsavorite and chrome tourmaline. tourmaline Regular green saturation rarely had the wonderful version of chrome.
This situation began to change in 1988, when a great discovery of a new type of chrome diopside and carrying was discovered in Russia. Known as chrome diopside, the material did not begin to reach the market until after the Berlin Wall fell in the final of 1989. But here, finally was a bright green gem at an affordable price - less than $ 100 a carat in smaller sizes.
The major findings of Russian diopside is in eastern Siberia, near the famous diamond mines. The diopside is colored by chromium, the same element that gives the color of ruby, emerald and alexandrite. The color was spectacular diopside Chrome literally glows green. However, there are some limitations to this jewel. First, chrome diopside may actually suffer from too much green - in sizes larger the pitch can be very dark. Care is required in cutting larger sizes to maintain shallow angles slightly to improve the brightness. But smaller sizes (under 2 carats), the color is exceptionally vivid and fresh.
The other limitation is that diopside is much softer than tsavorite garnet or tourmaline. At 5-6 on the Mohs scale, chrome diopside is not suitable for rings. But it is very suitable for earrings and pendants and is impressive when set in gold. Diopside jewelry should be stored carefully to avoid scratches harder stones.
