Description
Alexandrite is the rarest gemstone we stock and the only one that changes color outright — green by daylight, purplish-red under a warm lamp. It weighs 1.29 carats and measures 6.75 mm diameter, 3.9 mm deep, cut as a round brilliant. It reached us without a laboratory report, which is normal for colored stones at wholesale — we have described it from the stone itself and stated nothing we cannot see. 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, with our own inspection behind it.

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.
