3.96 ct Blue Oval Sapphire
This pair holds an enthralling strong blue colour finished off by a gorgeous clean cut. Once you set your eyes into both, it will be hard not to fall to its spell.
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.
