2.26 ct Blue Octagon Sapphire
Lovely sapphire in gorgeous blue colour and unique octagon shape. It’s a perfect stone for a beautiful sapphire pendant or ring.
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.
