Tanzanite is one of the most valuable and little known gemstones. It is a thousand times rarer than diamond because it is found in only one place: at the foot of Kilimanjaro, Tanzania. The name Tanzanite was introduced by the American jeweler Tiffany & Co. The light makes its color variable, being the most popular and appreciated its saturated-lilac blue tone.
