How to choose a loose opal

What should I check before buying?

Check the product description for gemstone type and construction, measurements and any disclosed treatment. For a stone intended for an existing setting, confirm its dimensions and suitability with your jeweller before ordering. A photograph alone does not establish size or classification.

How can I compare opal prices?

Compare the listed specifications and photographs together rather than choosing by carat weight alone. Read our opal value guide for buying context and our opal types guide for terminology. Contact us with the product reference when a detail needs clarification.
