Tanzanites are considered a 'single generation' gemstone. The gemstone was discovered around 1970 and there were initially 4 areas of mines (A, B, C & D Block). Today, there is only the D Block left that produces any material and that is a finite supply. They have not found tanzanite in any other area of the Merelani Hills, Tanzania.
