Tanzanite is the blue/purple variety of the mineral zoisite which was discovered in the Meralani (Merelani) Hills of Northern Tanzania in 1967, near the city of Arusha. It is used as a gemstone. Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet, and burgundy depending on crystal orientation.”

The term “semi precious” has been rejected by all the major gem trade organizations of the world including the CIBJO as it makes absolutely no sense whatsoever. I have sold alexandrites which, under the old semi precious/precious system are regarded as semi for prices up to $90,000 per carat – nothing semi about that is there. I recently sold a 21ct. demantoid garnet – which would have been classed as semi – for $22,000 per carat. The whole system of classifying gems in this way is absolute nonsense which why it has now been rejected by the professionals. I only wish it would people would realize that it has no meaning at all and that all gems are precious in their own right.
