Almost two carats of opal at a measured rate: that is what this listing offers. Before you order, here is what to go through.

• Weight: 1.90 carats, a good size for a pendant that gets noticed.
• Natural fire opal with play of colour. Look at it in daylight, then under a lamp, and tilt it to see the flashes travel.
• Hardness 5.5 to 6.5 on the Mohs scale. Expect surface marks over time if it is worn daily on the hand.
• Solid opal. When it arrives, look along the edge for a glued line, which would point to a doublet or triplet.
• Check for hairline cracks or cloudy patches; opal holds water and does not like drying out.
• Reference for WhatsApp: AG-000599.

Whole opal is normally left natural, though darkened opal is also sold in the wider market. Ask us what we know about this exact stone and we will tell you. If you want an independent lab report, you can arrange one. You may open the parcel and work through this whole list before paying.

This particular stone

This listing is one natural opal with a weight of 1.9 Carat. Its price is Rs. 4,500 — roughly Rs. 2,368 for each carat. Treatment: treatment not tested. Quote reference AG-000599 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome. As general background (not a statement about this stone): Solid opal is usually untreated; some opal is smoke- or sugar-treated, and doublets/triplets exist — we sell solid natural opal. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
