GIA Blue Sapphire 2.36ct Oval, Heated Natural Sapphire, 8.70 x 6.47mm

Classic, rich blue in a timeless oval — the kind of sapphire that anchors a piece and never goes out of style. GIA certifies this gemstone as a natural sapphire (corundum) with heat treatment noted on the report. Heat is a standard and widely accepted treatment in sapphire, and it’s commonly used to bring out the best possible color and clarity.

This is the exact sapphire shown, and the GIA report will accompany the purchase. If you’re dreaming of a custom engagement ring or an heirloom-style pendant, this stone is an excellent foundation.
