Before the cut

From rough stone to custom jewelry

Sapphire rough looks like frosted columns of blue, pink or yellow. We cut and set them into pieces made to last generations. Tell us if sapphire caught your eye and we will start your design.

What to look for

Velvety blue to violetish blue, medium to medium dark, strong to vivid.

Most have some inclusions. Very clean blue sapphires are rare and valuable.

Heating can deepen blue plus clear silk. Some induced orange colors fade in light, so ask for a lab report.

Fine stones in larger sizes rise sharply in price.
