Before the cut
From rough stone to custom jewelry
Ruby begins as deep red crystal in hard rock, often with hints of blue. We source cut rubies and design pieces around their fire. Tell us if ruby caught your eye and we will start your design.
What to look for
Pure, vivid red to slightly purplish red. Neither too dark nor too light.
Expect some inclusions. Value depends on how visible they are.
Heating can purify the red plus clear silky inclusions. Some stones have fractures filled with glass, so ask for a lab report.
Fine rubies above a carat are rare. Price climbs steeply with size.
