A 2.5 carat Australian opal suits the buyer who wants one noticeable stone rather than a cluster of small ones: a pendant wearer, or someone planning a ring that will be worn with some care. This is GS-000703, and it is in stock.

What you are getting

It is a natural fire opal from Australia, priced at Rs. 18,750, which works out at about Rs. 7,500 per carat. Opal is valued mainly on how its colour behaves when you turn it under light, so the live photographs matter more than any adjective we could add. Look at them in daylight if you can, and ask on WhatsApp for a short video of the stone moving.

On treatment, be sensible. Solid opal is normally sold as it came from the ground, but smoke and sugar treatments exist, and so do doublets and triplets. We sell solid natural opal only. Ask us about this exact stone and we will tell you what we know; independent lab testing can be arranged on request.

Wearing it

With a Mohs hardness of 5.5 to 6.5, opal is softer than quartz, so keep it away from knocks and abrasive dust. A pendant or earring is the easiest life for it; a ring is fine if you remove it for housework. Browse the rest of our loose opal range to compare nearby sizes.

Pay Cash on Delivery once you have opened the parcel and seen the stone yourself, anywhere in Pakistan, with 7 days to return it if you change your mind. Before you choose, read our gemstone buying guide.
