Some presence, without paying for a very large stone: that is what a 1.40 carat fire opal gives you. Here is what is worth knowing before you order.

• It weighs 1.40 carats and is a natural fire opal with play of colour.
• The effect shifts with the light, so look at it in daylight as well as indoors.
• Hardness is 5.5 to 6.5 on the Mohs scale, softer than most stones used in rings.
• It is solid opal, not a doublet or triplet. When it arrives, look at the sides in good light; a doublet shows a join line.
• The reference to quote on WhatsApp is AG-000589.

Whole opal is mostly sold as nature left it, but darkened stones are around in the market. Ask what we know about this piece and we will answer plainly. If you want an independent lab report, you are free to arrange one. Opening the parcel before you pay gives you the chance to check everything above for yourself.

The rest of the opal collection is one click away, and our opal guide is a useful read.

This particular stone

This listing is one natural opal with a weight of 1.4 Carat. Its price is Rs. 3,750 — roughly Rs. 2,679 for each carat. Treatment: treatment not tested. Quote reference AG-000589 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.
