Studs, a bezel pendant or a slim bracelet charm: those are the pieces a 1.55 carat opal is made for. It is a small-to-modest size, the kind that suits light, slightly dressy jewellery you can wear often. It is less suited to a big cocktail ring, where a larger stone carries the look.

This one is solid natural opal, reference AG-000582. At this weight it is more about colour than size, so ask us on WhatsApp for a short video and watch how it behaves when it moves. That will tell you more than any photo.

Checking an opal

Look for hairline cracks. Turn the stone through several angles. Make sure it is a solid stone and not a thin slice glued onto a backing; ours are solid, but it is a good habit. Smoke and sugar treatment happen in the trade, so ask us about that too. And remember opal is only 5.5 to 6.5 on the Mohs scale and carries water inside, so heat and harsh cleaners are best avoided.

More stones are in the opal collection, and our opal guide fills in the background.

Cash on Delivery means the rider waits while you check it. Karachi deliveries usually take 1–2 working days and other cities 2–4, with 7 days for returns.

This particular stone

This listing is one natural opal with a weight of 1.55 Carat. Its price is Rs. 4,500 — roughly Rs. 2,903 for each carat. Treatment: treatment not tested. Quote reference AG-000582 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

Under two carats, a stone like this sits neatly in a slim ring, a stud or a delicate pendant and does not snag on sleeves. It is also where many first-time buyers begin when a stone is recommended for astrological reasons, because the total cost stays modest.

On the Mohs scale opal rates 5.5 to 6.5. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy opal from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone. We check every opal for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
