View Sample & PricingTanzanite Stone has seen a rapid increase in popularity in the last few years. Its mineral name is Zoisite and is naturally reddish brown in color, it is through heat treatment that it achieves its beautiful blue to violet color.
Tanzanite was discovered in 1967, at the foot of Mt. Kilimanjaro in Tanzania (which gave the stone its name). Tanzanite is a pleochroic gemstone, meaning it can appear to have different colors under different light. In natural light, the stone resembles Sapphire in color, however in fluorescent light, it is closer to Amethyst in color. They are naturally trichroic, meaning the show blue, red-violet and yellow-green colors depending on the light on its three crystal axes.
The blue to violet color is their most coveted property. It is rare to find a naturally blue stone in the rough, so most achieve their color through heat treatments. The stone is heated to 500-600 degrees Celsius for about half an hour.
Tanzanite is the most prized Zoisite, but not the only one. Here are some others worth mentioning:
It is safe to assume that all rich blue Tanzanite have been submitted to a stable heat treatment.
Tanzanite Stone hardness rages from 6 to 7 on the Mohs scale. However, it has a tendency to cleave and is rather brittle, which is not ideal for daily wear. Tanzanite are best used in occasional pieces or behind protective settings. They should be cleaned with a soft brush, mild detergent, and warm water.
