0.328ct Tanzanite Loose Stone from Tanzania
Tanzanite is a stone characterized by its "pleochroism," where it appears to change color depending on the viewing angle. The way various shades of blue, such as blue, bluish-purple, and ultramarine, dance within the stone is truly captivating and never gets old. Notably, Tiffany & Co. was the one who named this stone "Tanzanite."
This tanzanite boasts high transparency and offers a beautiful brilliance, thanks to its deep color and meticulous cut. It features a precise cut that minimizes color fading even when viewed from the front.
