Description
An opal that holds broad sheets of blue and sea-green play-of-color right across the dome rather than in isolated pinfire specks. It weighs 1.27 carats and measures 7.51 x 6.16 x 4.18 mm, cut as an oval cabochon. It reached us without a laboratory report, which is normal for colored stones in the trade — 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 within the US, with our own inspection behind it.
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. If you need additional images, daylight videos, or comparison photos, we’re happy to provide them before purchase.
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?

Yes. We offer short-term 24–48 hour reservations for serious buyers. Longer holds may be available on a case-by-case basis.
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.
