Description & History
Tanzanite was discovered in 1967 and is celebrated for its mesmerizing blue-violet hues and unique trichroism—showing three distinct colors depending on the viewing angle. Found in only one location on Earth, it is over 1,000 times rarer than diamonds. Tiffany & Co. helped popularize it globally, naming it after its country of origin, Tanzania.
