0.87 ct Round Yellow Sapphire
The bright yellow colour makes this gemstone so lovely to look at. It is like adding touch of sunshine to a lifeless piece of jewelry.
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.
