Mention opal to most gem buyers and Australia comes to mind, and dealers in Pakistan have known that for a long time. Australian opal is the reference point for the species, and customers often ask for it by origin before they ask about colour. That is a trade habit, not a rule: origin tells you where a stone came from, not how good it looks.

This 2.1 carat stone is a natural fire opal from Australia with play of colour. Its reference is AG-000603, and we are happy to send a short video so you can see the colour for yourself.

Facts and cautions

Hardness is 5.5 to 6.5 on the Mohs scale, so handle it gently and favour a pendant or a bezel setting. Opal that is solid throughout is normally left natural, but smoked or sugar-treated stones and doublets or triplets exist. We sell solid natural opal only. Write to us on WhatsApp for what we know about this exact stone; independent lab testing is up to you.

Compare it with other pieces in our opal collection, and read our gemstone buying guide before you choose.

Open the box with the rider there, look at it in good light, then pay. Karachi orders usually arrive in 1–2 working days, the rest of Pakistan in 2–4, with 7 days to return.
