Color Change Garnet from Tanzania. Strong shift from purple in daylight to red under incandescent light. This rare garnet variety owes its optical effect to trace element chemistry, most often chromium and vanadium, and is highly prized for its dramatic two-color personality. Tanzanian sources have produced some of the finest examples of color change garnet on the market, rivaling those from Madagascar and Sri Lanka.
