5.06 ct Blue Cushion Sapphire
A pair of strong blue sapphire, very gorgeous cut and a lot of spark. With this as center stone to drop earrings, you’ll have something to treasure for a long time.
More care is needed with treated stones.
Sapphires can be treated to improve colour by a process called diffusion. Older stones treated in this way may only have treatment near the surface, so if you become aware that you or a customer has a stone treated in this way avoid repolishing.
