10 mm Lab-Grown Green Emerald – Heart Cut – Eye-Clean Quality

This 10 mm lab-grown emerald shows a green hue, cut as a heart. It is graded Eye-Clean on Stuller's quality scale — a calibrated stone cut to a standard millimeter size rather than a one-off crystal.

Because it is calibrated, we can usually replace or match it — useful for a pair, or if you want the same look in another size. Set it as the center of your own ring in our ring builder, or buy it loose and keep it for a design of your own. Every stone ships insured, worldwide.

To preserve the beauty and longevity of your gemstone, we recommend gentle care. Clean the stone using warm soapy water and a soft brush, avoiding harsh chemicals or ultrasonic cleaners unless the gem type is known to be safe for those methods. Store your jewelry separately in a soft pouch or box to prevent scratches from harder materials. Always remove gemstone jewelry during vigorous activities—such as exercising, swimming, or using household cleaners—to protect it from impact, heat, and chemical exposure. Regular professional inspections are encouraged to ensure settings remain secure and the stone stays in optimal condition.
