Ruby

Ruby Rings and Jewelry in Grand Cayman

The most intense red in nature, at hardness 9, set in 14-carat and 18-carat gold.

The Strongest Red

Rarer Than Diamond in Large Sizes

Ruby is the most intense red in nature and, like sapphire, it is corundum at hardness 9, so a ruby ring is tough enough to wear often. It is the same mineral as sapphire; only the red variety earns the name.

Fine ruby is rarer than diamond in large sizes, which is part of its lasting appeal for statement rings and anniversary pieces. Above a couple of carats, genuinely vivid untreated material becomes very hard to find, and price rises steeply with saturation rather than with weight alone.

We set ruby in 14-carat and 18-carat gold, most often with white diamonds around it, since the contrast makes the red read hotter. Yellow gold warms the stone further; white metal keeps it crisp.

Questions

Good to Know

Is ruby durable enough for everyday wear?

Yes. Ruby is corundum, the same mineral as sapphire, at 9 on the Mohs hardness scale and second only to diamond. That makes a ruby ring one of the few strongly coloured stones you can wear regularly without special care.

What makes one ruby more valuable than another?

Colour saturation above all. The most valuable rubies are a vivid, pure red without brown or purple cast. Size then multiplies that: fine ruby is rarer than diamond in large sizes, so price climbs sharply once a vivid stone passes a couple of carats.

What is the difference between ruby and pink sapphire?

They are the same mineral, corundum, separated by depth of colour. Once the red is strong enough it is called ruby; lighter material is pink sapphire. The boundary is a judgement call, which is why a strong pink sapphire can be excellent value next to a pale ruby.
