2.02 ct Blue Octagon Sapphire
A sapphire from Sri Lanka so full of life and lustre. Very exquisite with its blue colour and octagon shape.
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.
