One of the rarest stones in the world, Tanzanite is a thousand times more rare than diamonds. It belongs to the Zoisite class of gemstones, and is one of the latest discoveries in the age old tradition of gemstone jewellery. Tanzanite was first discovered in 1957 in Tanzania, from which it derives its beautiful name. A good quality tanzanite stone is known the world over by its brilliant blue shade. More accurately known as ‘ultramarine’, the color is sometimes sapphire blue, wherein the blue tinge comes from presence of the rare element Vanadium.
