It's rare to see tanzanite, a blue variety of the zoisite mineral, of this caliber anywhere. From a stonecutter's perspective, tanzanites are being cut deeper and deeper because the pigment of the new mined material is so thin and poor.
That is not the case with this 4.5 ct tanzanite measuring 11mm wide x 13mm long. With approximately 1.5 carats of fine kite-shaped side diamonds. Tell-tale red flashes throughout the stone are a sign of the very best gem material. Condition report: table facets of the tanzanite exhibit light to medium wear... which can be easily polished out.
Marked 950 Platinum. Currently size "6," but easily resized by CHURCHILL.
