Although some dealers may tell you they have unheated stones, it is best to take this with a pinch of salt. The accepted wisdom is that all Tanzanite is heated. Unheated the stone is a brownish colour and only after heating does it go blue/violet. Some crystals have admittedly been heated in the ground and are already blue but will generally be heated again anyway as the color always improves further. Stones are heated at 600 degrees celcius in a gemological oven for a short time. Further information is available at <a href=http://www.lapigems.com/tanzanite.asp</a>

It's just a name assigned to this color stone from Jewelry Television (JTV) with their trademark on it. They used to call it green tanzanite and claimed that it was a cross between tsavorite and tanzanite and now they are saying that they don't know what causes this color.

Actually neither term is correct. Tanzanite is a variety of the mineral Zoisite. Quartz and Diamond are minerals in their own right and there is absolutely no connection between the 3 of them. They all have unique physical and chemical properties. Anyone trying to sell "Tanzanite Quartz" is most likely selling Amethyst (Amethyst is the purple variety of Quartz) and anyone selling Tanzanite Diamond is simply being unscrupulous. There is no such thing. You might want to learn more about Tanzanite here on www.lapigems.com as they have extensive educational features.
