Opal has a reputation for being delicate, and that reputation is partly deserved, so this section is about living with it. This Australian fire opal weighs 4.1 carats and is graded 5.5 to 6.5 on the Mohs scale. In a pendant, that is rarely a problem. In a ring, scratches are likely over time unless you take care.

The stone is a natural fire opal from Australia, SKU GS-000732, priced at Rs. 18,750, or about Rs. 4,573 per carat. That sits at the upper end for this batch, which is common with Australian opal.

Look after it by cleaning only with lukewarm water and a soft cloth. Avoid ultrasonic cleaners, steam and heat, since opal holds water in its structure and dislikes sudden change. Wrap it separately from harder stones when you store it, and put it on last when dressing, after perfume and hairspray.

Treatment is the final thing to ask about. Solid opal is usually left as mined, though smoke or sugar treatment exists and doublets and triplets are traded. We sell solid natural opal; message us for what we know. More options are in the opal collection.

Cash on Delivery is available across Pakistan, so you inspect the stone before paying, and returns are accepted within 7 days of delivery. Before you choose, read our gemstone buying guide.
