Tantalising Tanzanite: The Ultimate Blue Gem

More than half a century after its discovery, we bring you the history of tanzanite, the alluring blue gem whose colours range from deep blue to lilac.
(The Jewellery Editor)

"Unknown to the world only a generation ago, tanzanite has firmly established itself in the firmament of precious gemstones thanks to its alluring rich blue and deep lilac hues. Shortly after it's discovery in Tanzania, it was ushered into the limelight by Tiffany & Co, known for its interest in unusual new gems...."

Note that as the article indicates, most Tanzanite is removed from the ground in its natural color, which is a variation of brown. Most of it therefore has to be heated to produce the beautiful blue and purple one recognizes as Tanzanite. However, on rare occasions, it can be found already in a blue state, as it was naturally heated with no human intervention. Since we typically purchase our Tanzanite in the rough and would heat it ourselves, we have a few natural blues, such as our large 24.97ct Certed Oval (there is a natural needle inclusion within this gem that can be seen under magnification that also indicates natural heat/color as if done in an oven, the needle would most likely have broken the piece of rough or faceted gem); the 5.25ct fancy shape faceted by one of our award winning cutters (crystal was blue as can be seen when purchased and typically wouldn't have been heated); and we suspect the unique 3.40ct blue also faceted by the same cutter noted previously and published, is believed to be natural color. The magnificient 4.60ct Green/Teal Emerald cut (again faceted by an award winning cutted noted previously) was published in a book, and that piece is unheated - if heated, it would lose its importance and unique color. With respect to other fancy colors, the orange trilliant (4.93ct) is entirely natural and rare in color, and the 1.96ct pear is of a typical color of entirely natural unheated Tanzanite and would turn to a nice blue if heated. Finding one of this color that hasn't been heated is not common. Note that prices for Tanzanite have risen dramatically, and our pricing is out of step with what is seen on the market currently. Consider your Tanzanite purchase now - rough and cut is not coming out of Tanzania due to restrictions.
