Chatham-Created Antique Cushion Rubies
We will price match any legitimate Chatham retailer
Rubies and sapphires both belong to the gem species corundum. It is the presence of the trace mineral chromium that gives rubies their rich red color. Rated 9 on the Mohs scale of hardness, rubies are very durable, making them ideal for use in jewelry.
Eco-Friendly antique cushion cut Chatham lab-created rubies are not fakes, rather they are REAL rubies grown by the flux method in a laboratory. This means they grow in the same crystal structure as mined rubies. So they exhibit the same chemical, optical and physical properties as the finest natural rubies. With Chatham, you get top quality, top color rubies for a fraction of the price of natural rubies. If you have any questions, please don’t hesitate to call our staff gemologist at 970-535-4139.

Antique cushion weights are similar to those of emerald cut. Pictures not actual size. Sapphire is denser than diamond, so it weighs more for the same physical size. Because carat is a measurement of weight, not size, it's important to order colored stones based on physical size rather than carat weight.
