Comment: Cut-to-match set from same rough, and the two best selected for a pair. Exceptional color-play from pleochroism with green, violet, purple, and blue in ever-changing patterns and combinations. Also refered to as petrol-colors. Such untreated tanzanite (zoiste) has gotten more attention over the years with the blue-blue heated variety somewhat over-chewed and out-marketed. These two will make for a pair of sparkling color magic, best set with freedom to move. Any type of gold will do. Alternatively to earrings, they are with 7x5mm not yet too big for sidestones, perhaps around a green or blue center gem. Ask us for ideas to make a once-in-a-lifetime piece of magic personalized jewel.
