3.61 ct Oval Blue Sapphire
A beautiful 3.60 ct oval blue sapphire in a lively sky blue colour. This stunning stone would make a perfect sapphire pendant especially if paired with a couple of diamonds.
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.
