Gem Info

  • Colour : Blue

Blue or violet varieties of zoisite are also called tanzanite.

Tanzanite forms as a brownish crystal and is trichroic - which means it shows three colors - brown, blue and violet concurrently. Heating, either naturally underground by metamorphic occurrences or artificially in a furnace, removes the brown or burgundy color component to produce a stronger purplish-blue color and makes the stone "dichroic" which means it only reflects blue and violet. Rarely, gem-quality tanzanite will heat to a green primary hue, most often accompanied by a blue or violet secondary hue. These green tanzanite have some meaningful value in the collector market, but are seldom of interest to commercial buyers.
