Before the cut

From rough stone to custom jewelry

Aquamarine begins as pale blue-green crystals beneath the earth. We select the clearest cuts for rings that hold the color of the sea. Tell us if aquamarine caught your eye and we will start your design.

What to look for

Look for even blue with no zoning. It is most striking above 5 ct.

Most faceted aquamarines are eye clean. Expect good transparency.

Untreated, much aquamarine is blue green. Controlled heating removes the green for a purer blue.

Large sizes are easy to find. Small accent stones tend to be paler.
