Today, Chatham lab-grown emeralds are highly regarded for their color, clarity, and overall appearance making them a popular choice among consumers seeking high-quality gemstones.

Chatham lab-grown emeralds are chemically, physically, and optically identical to their mined counterparts. They offer a responsible and more affordable alternative to mined emeralds without compromising on beauty or quality.

The Chatham Standard

Quality That Matters

Color

Chatham lab-grown emeralds display the same vibrant green color, ranging from a slightly bluish-green to a more intense and vivid green, as its mined counterpart.

Generally, the smaller the stone, the less color saturation. Likewise, the bigger the stone, the deeper the color.

Clarity

The standard clarity grade at Chatham is Gem Quality. That means the gems are free of any eye-visible inclusions.

Our gemstones grow as-is; they do not include any clarity enhancements or treatments to improve their quality.

Cut

Each lab grown gemstone is carefully hand-cut and rigorously inspected before reaching your hands. Chatham uses a mix of brilliant and step faceting styles, depending on the shape, to maximize brilliance and color uniformity.
