Care instructions

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.

FREQUENTLY ASKED QUESTIONS

Are your gemstones natural, and how do I know they’re authentic?

Every listing states whether a stone is natural, lab-grown or cultured. When a stone has a lab report, the lab and report number are on its page; when it has none, its page says so.

Do the photos and videos accurately show the gemstone’s color?

We use controlled lighting and professional equipment to capture true-to-life color. However, screens may display colors differently. The photos and video on each listing are of that exact stone and are the media we have for it. We don’t take additional images or videos on request.

Is certification included with every gemstone?

No. Many stones come with a lab report; when one does, its page shows the lab and report number. When a stone has none, its page says “No independent lab report included.”

Can I reserve a gemstone before purchasing?

We aren’t able to hold or reserve stones. Our gemstones move quickly, so the surest way to secure one is to place your order. Each stone’s return window is listed on its page, so you can see it in person with confidence.

Do you offer gemstone sourcing if I don’t see what I’m looking for?

Absolutely. Through our network of trusted dealers, we can locate specific gemstones based on your preferred budget, treatment level, origin, shape, and size. For stones we source for you, we can share additional photos and video before you decide.
