The history and origin of Tanzanite
Tanzanite is a relatively new gemstone, discovered in 1967. It is said that Masai tribesmen walking through the plains of Tanzania came across a stone that was seen to be hit with lightning. This mineral was Zoisite and the mineral was a beautiful deep blue with a tinge of purple surrounding the center. This new mineral was later named Tanzanite with the help of Tiffany’s and Co. and from this point on became a favorite of the jewelry marketplace.
Tanzanite comes from one place only, the mines of North Tanzania. It is an extraordinary mineral in that it gives off a wonderful hue, most notably deep blue with a hint of purple. However, it can come in other colors as well including purple or brownish yellow.
Some of the stones even include a trichroism effect, meaning they can reflect three different colors depending on the angle which you look at the stone. Usually they include a purple, blue and yellow or green.
Tiffany’s made this gemstone extremely popular to the world’s gemstone marketplace and due to mainly its undeniable beautiful color; it has become a favorite around the world. Because Tanzanite is rare and found in one place only, it can command high gemstone prices that sometimes rival or approach that of the diamond.
Tanzanite is marketed as the gemstone to give to a mother with a new born child. The Masai of Africa believe that this stone brings life and Tiffany and Co. has marketed this idea to millions making it a great gemstone for new mothers.back to menu ↑

Tanzanite is an ultra-beautiful gemstone that is very rare and full of attractive attributes. This gemstone was found in Tanzania in 1967 and has become extremely popular around the world because of its wonderful hues, most notably blue encircled by a hint of purple.
Tanzanite comes from the mineral Zoisite. It is made from calcium, aluminum and silica. Tanzanite is only available in one distinct location, while it is known that specific trace minerals have caused the wonderful color of Tanzanite, it is not copied naturally in any other location throughout the world. Zoisite can come in many colors; however, Tanzanite is usually sold when it is either blue, bluish violet or blue with a hint of purple surrounding it.
Besides forming naturally, Tanzanite can be synthetically created. It is interesting to note that when Tanzanite is created synthetically it is no longer has the mineral properties of Zoisite; it has different mineral properties called Forsterite. Practically all Tanzanite is treated whether synthetically or natural. It is usually heated with temperatures over 500 degrees Celsius. This treatment process enhances the color of the stone and makes it perfect for any fine jewelry setting.
Today, Tanzanite is one of the more popular and valuable gemstones available. It is said to sometimes command prices that diamonds do. However, it does have a few shortcomings including the fact that it is not that hard, with only a score of 6.5 to 7 on Mohs hardness scale. It can also lose its color to extreme heat. While normal wear and tear shouldn’t affect the color of the stone, it has been known to change slightly.back to menu ↑
