Weighing
Every stone is weighed on a digital carat scale that reads to a hundredth of a carat. That weight goes on the listing as the scale shows it, never rounded up.
We then convert it to ratti, because that is how many buyers here think about size. We use the standard gem ratti: 1 ratti equals 0.91 carat. A 4.55 ct Neelam, for example, is 5 ratti. Some sellers use a smaller ratti, so the same stone can sound heavier elsewhere. Our ratti converter explains the difference and lets you check any figure.
Photographing
Each stone is photographed on its own, under steady light, so the photo on its page is of the stone you will receive. We do not use stock images or pictures of a similar stone. We try to keep colour true, but every phone and computer screen shows colour a little differently, so expect a slight shift between screen and hand.
Basic gemmological checks
We are a shop, not a lab. Still, a few simple checks sort out most problems before a stone is listed.
- Loupe. A 10x loupe shows inclusions, growth lines, gas bubbles and polishing marks. Natural stones usually carry small signs of how they grew, while glass and many imitations look quite different under magnification.
- Refractometer. Where a stone has a flat polished face, we measure how it bends light. Each gem species falls within a known range, so this helps tell sapphire from glass or from a look-alike stone.
- Specific gravity. For some loose stones we compare the weight in air with the weight in water. This is useful for cabochons and beads, where a refractometer reading is harder to get.
- UV light. Some gems glow in a typical way under ultraviolet light. Many rubies, for instance, glow red. We treat this as a supporting clue, never as proof on its own.
Not every test suits every stone. Opaque stones like Aqeeq, lapis and malachite are checked mainly by eye, loupe and specific gravity. Soft or porous materials such as pearl, coral and amber are handled gently and kept away from anything that could harm them.
Why we say "not tested for treatment"
Many gemstones are treated in the trade. Sapphire and ruby are often heated, emerald is often oiled, and some stones are dyed or filled. A few treatments show under a loupe. Many do not, and can only be identified with the equipment of a properly equipped gem lab.
We do not have that equipment, so we do not guess. When a stone has not been lab-tested for treatment, its page says so in plain words. We will not call a stone unheated or untreated without a lab report that says it. If treatment matters to you, and for a costly stone it often should, plan to have it tested.
Testing a stone yourself
You are welcome to take any stone to a gem lab of your choice, and our 7-day return window gives you time to do it.
- Receive the stone and keep it unset.
- Take it to a lab you trust within 7 days of delivery.
- If the lab finds it is not the natural gem we described, message us from the Contact page with a copy of the report.
- Send the stone back and we refund in full, including delivery.
We have no partner labs, we do not recommend any particular one, and we do not issue papers of our own. What we offer is a clear description and a straightforward refund if a lab shows we got it wrong. The full terms are on our returns page.
