Well the mineral Tanzanite, a the blue/purple variety of the mineral zoisite, discovered in the Meralani (Merelani) Hills of Northern Tanzania in 1967, is very beautiful and as it is ONLY found in this one place (and the deposit is running out), it could be regarded as the most rare gemstone mineral.

However, you could argue that the blue 'Hope' diamond or a large pink diamond is the rarest and most beautiful mineral.
