2.20 ct Purple Oval Sapphire
This unheated gemstone is undeniably gorgeous. The rich vibrant purple colour makes a lot of difference and you can see the tiny bright flashes all around as if they are screaming take me.
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.
