Before a gemstone becomes yours.

A few details worth checking when choosing a sapphire, ruby or another stone for your collection.

Does every gemstone have a laboratory report?

Reports are specific to individual stones and are not included with every listing. Check the product’s laboratory details and ask for clarification or a report copy where available. The laboratory logos on this site do not certify every gemstone.

How can I check whether a stone is heated or treated?

Read the treatment statement in the individual listing and its available report. “Natural” describes a gemstone’s origin and does not by itself mean unheated or untreated. Our heated and unheated sapphire guide explains what to look for.

Can I see a gemstone in motion?

Selected stones have product videos. Use the films on this page or open the product gallery to see the media available for that stone. If you need another view or have a question about color, send us the product link. Screen settings and lighting can affect the color you see.

How do I enquire about a collector gemstone?

Contact us with the product link or reference and the details you would like to confirm. Discuss the stone’s availability, documentation and purchase arrangements before proceeding. Checkout is also available on eligible listings.

What should international collectors check before buying?

Confirm your delivery destination, displayed currency, shipping method, insurance arrangements and any import taxes or duties before purchase. Read our shipping policy and contact us about the arrangements for the specific stone.

What return terms apply to a gemstone purchase?

Read the current refund policy before buying, including eligibility, time limits and the form of any refund or credit. Ask us to clarify any terms that affect your decision before you place an order.

Which stone will you keep coming back to?

Explore the collector selection, then take a closer look at the details.
