3 Pieces Natural Tanzanite 0.62ct 3.8mm Round Cut #37

This trio of natural tanzanite round cuts captures the gem's famous pleochroism beautifully. Photographed side by side, the three stones reveal a delightful tonal range: the first glows with a deep violet-purple warmth, the second sparkles with a lively teal-blue brilliance, and the third settles into a soft, silvery lavender. Fine needle-like silk inclusions are visible under magnification, as is typical for natural tanzanite and a reassuring sign of authentic origin.

Sourced from the Merelani Hills of Tanzania, the only place in the world where tanzanite forms, these stones have been heat-treated using the standard practice that reliably develops the classic blue-violet hue. The trio works beautifully as matched accent stones in earrings, a three-stone ring, or a pendant cluster.
