Comment: Precision cut giant multicolor natural zoisite (tanzanite). Not to be compared with the fried-brittle see-everywhere blue tanzanite in department stores. This is the real gem, pretty by nature as it is rarely found. Fantastic precision cut by Peter, top-of-world in an exclusive size and rare quality. Not photogenic but extra nice shimmering glimmer in person. No inclusions whatsoever even under lens. Collector gem. Not cheap. Never dark, never pale, always interesting and with surprising new color combinations from metallic green, via purple and violet to petrol colored iridescence. Pendant size.
