Top Tanzanite

  Tanzanite, a blue form of the mineral zoisite, is an extraordinarily attractive gemstone prized for its rarity and hue. It is common to be inquisitive about the tantalizing color of this gemstone. Its exquisite, velvety color spans from deep violet-blue to subdued purple tones. When seen from various angles, it reveals distinct hues, thus making it rare and desirable.  Geological Formation Small concentrations of vanadium and chromium, which were present throughout its formative years inside the earth's crust, give tanzanite its famous blue and violet colors. When this mixture is heated to around 600 degrees Celsius, the oxidation state changes, which creates or accentuates the tanzanite's blue hue. Almost all tanzanites today have a rich, velvety blue hue, however, this is mainly due to artificial heat treatment. Only a small percentage of tanzanites on the market now have a blue tint that was created naturally from metamorphism heat.  Shop Now » Rings Earrings Bracelets The

  Tanzanite, the gorgeous violetish-blue gemstone first discovered near the foothills of Tanzania's majestic Mt Kilimanjaro, was declared as one of the official  December birthstones  in 2002 by the American Gem Association. The gem is a wholly unique mineral that formed about 500 years ago under intense geological circumstances and is found in just one location across the globe. This, paired with the predicted exhaustion of tanzanite in the next 25 years, adds to the stone's attraction.  The Masai tribes of Tanzania have known about the purple-brown mineral long before the west discovered its violetish-blue variation in 1967. Approximately 97% of tanzanite is purple-brown in its natural state. This is because volcanic activity under the earth's crust altered the hue of tanzanite millions of years ago. The remaining 3% is naturally blue which is extremely uncommon. As a result, tanzanite is frequently heated to create its gorgeous color. Initially, the people of the tribe u
