In its rough state, tanzanites appear reddish brown. Since tanzanites are valued for their blue violet shade, the stones are heated to 500° Fahrenheit to eliminate the brown orange color. While most other gemstones such as sapphires and rubies are heated to enhance their clarity, tanzanite heating only brings out the color present in the stone and does not create a higher quality gemstone.

Where is Tanzanite found?
Tanzanite is created under conditions that are so geologically unique that there is less than a million to one chance that it will happen again. Unlike other gemstones, Tanzanite is only found in one place—in the entire world—Tanzania, at the foot of the majestic Mount Kilimanjaro.
Mount Kilimanjaro is one of three freestanding volcanic peaks that are the result of massive tectonic activity that created one of the most minerally abundant places on earth known as the Mozambique Orogenic Belt. With all of the folding and faulting that took place millions of years ago, different combinations of minerals were able to form and reform, producing Africa’s rich gemstone deposits.
The area where Tanzanites are found is small and covers an area of only 4 square kilometers. Since the supply is so limited and because it is unlikely that another deposit will ever be found again, the world’s supply of Tanzanites will be depleted in 10 to 15 years.

Tanzanite is a relatively new gemstone and was not discovered until the 1960’s. According to legend, tanzanites first became noticeable when lighting started a fire that swept through the hills surrounding Mount Kilimanjaro. Masai herders noticed the newly developed blue color and began to collect the crystals.
Around five years later in 1967 Manuel D’Souza, a hobbyist prospector, came to Tanzania in search of rubies. A local told him about the beautiful blue stones so D’SouZa, thinking they were probably sapphires filed his mining claim.
When he first began mining the crystals he had no idea what they were. On his mining claim he incorrectly identified the crystal as olivine (also known as peridot). Other prospectors soon followed his lead and began filing incorrect claims for cordierite, epidote, and dumortierite. Not long after, the Tanzanian government geologists finally identified the crystals as Zoisite.

It was also D’Souza who offered exclusive rights to Tiffany and Co. Tiffany’s launched a wide spread publicity campaign in 1968 and changed the name of the newly discovered zoisite to tanzanite. The named was changed because the technical name, blue zoisite resembled the English word suicide. Tiffany’s eventually abandoned tanzanites because prices fluctuated so erratically due to poorly managed supplies.
