Lab-Grown Ruby

Mineral: Corundum | Hardness: 9 | Birthstone Month: July | Anniversary: 15th & 40th

Twenty two years after the growth of emerald, Carroll Chatham grew his second gemstone: Ruby.

In 1958, Chatham revolutionized the industry yet again with lab grown ruby. Chatham's ruby creation is a vivid red, ranging from a deep, rich crimson to a bright, fiery red. These gemstones exhibit excellent clarity and brilliance, completely free of any color treatments to enhance its beauty.

For the bold and daring, Chatham lab-grown ruby offers a responsible and more affordable option to mined rubies, while maintaining the same physical, chemical, and optical properties.
