A stunning and rare YELLOW zoisite crystal, often called "yellow tanzanite" in the trade, from the same locality as the classic blue and purple tanzanite crystals but much more rare, perhaps 1 in 1000. The luster is insane, like cleaned glass, and the crystal has textbook perfection. Really, it looks carved. This is a small miniature size, impactful and impressive when on a shelf for the reflections it throws off as light hits the brilliant surfaces. 19.6 grams
