What does a GIA report confirm on a blue sapphire?

A GIA report independently confirms the stone is natural corundum, states whether it has been heat-treated, and for many stones offers an opinion on country of origin - independently verifying claims rather than relying on the seller's word alone.

Are these blue sapphires heated or unheated?

Both appear in this collection. Treatment status is confirmed on the GIA report and stated plainly on every product page - unheated stones are rarer and typically priced at a premium over heated stones of comparable size and color.

Where are these blue sapphires from?

Most of the blue sapphires in this collection are sourced from Sri Lanka (Ceylon), long regarded as a premier source of fine blue sapphire, with additional stones from other origins. Origin is disclosed on each product page.
