BUY WITH CLARITY

Look closer. Ask better questions.

Our four October listings bring actual stone photographs and individual specifications together. Report information varies from stone to stone.

Photographs of the stone

Use the product photographs to explore the individual gem. The campaign imagery on this homepage is illustrative and is not a photograph of inventory.

Treatment, clearly described

For the October selection, listings distinguish owner-reported treatment details from information in a supplied laboratory report. Read the evidence for your chosen stone.

More information before deciding

Contact us with the product name or Stone ID if you need another photograph, a measurement or clarification about available reports.

A SHORT BUYING GUIDE

Choose beyond the carat weight.

Compare the whole stone, not just its size or asking price.

Colour & appearance

Start with the colour you enjoy. Look at photographs and ask about appearance under different lighting; a screen image cannot show every detail.

Cut, shape & dimensions

Carat describes weight. Compare dimensions and shape as well, especially if the stone is intended for a setting. Cut influences how a gemstone presents its colour and light.

Treatment & report information

Compare treatment disclosures and available laboratory information alongside weight and appearance. An owner description and an independent laboratory report are different sources of evidence.

More buying questions
Does every stone have a laboratory report?

No. Available report information varies by listing. Some of our current stones have owner-reported details and a report is pending or has not been supplied. Check the individual product page and ask us if anything is unclear.

What does “unheated” mean on a listing?

It describes the stated treatment status. For the October selection, the listing explains whether this comes from the owner’s description or a supplied report indicating no evidence of heating. These are not interchangeable forms of verification.

Are jewellery settings included?

Our current October products are loose gemstones. A ring or mounting shown in a photograph is not included unless the product description explicitly says so.

Where are the current stones dispatched from?

The four October stones are held in Sri Lanka and can be dispatched from there. Send your destination country to discuss delivery arrangements, charges and any carrier or insurance requirements. Delivery timing and returns terms should be confirmed before committing to an order.
