This Montana Sapphire reveals a bright, complex color that shifts between teal and blue depending on the angle, giving it a dynamic, living quality in hand. Cut by American cutter Barbara Thomas into a modified fancy triangle—hovering between a cut-corner triangle and a soft hexagon—it carries a uniquely modern silhouette that feels both geometric and organic.

Measuring 10.2 x 8.8mm and weighing 4.08 carats, this is an unusually large gem for Montana Sapphire. It is near loupe clean, with only a few tiny needle inclusions that trace its crystal growth, along with a few very small inclusions visible under 10x magnification. Treated with heat-only by our team, this one-of-a-kind gem will make an incredible statement piece.
