A natural sunstone of 7.55 carats, about 8.30 ratti, at Rs. 2,030 – roughly Rs. 269 per carat. Sold loose.

The longest, narrowest stone in the category

Measured from the photograph, this one is about 1.75 times as long as it is wide, where the most balanced stone in this tray measures 1.19. That makes it a distinctly slim oval, and it changes what the stone suits: it hangs well as a pendant, sits along the finger in a ring rather than across it, and needs a setting made for those proportions rather than a standard oval mount.

Why polish matters so much on sunstone

More than on most stones, and for two reasons.

The first is optical. The glitter you are buying comes from copper platelets inside the stone, and light has to get in and back out to reach them. A clean, well-finished dome lets it; a dull surface scatters the light before it ever gets there, and the sparkle simply disappears.

The second is that sunstone is soft. At Mohs 6 to 6.5 it is softer than the quartz dust in ordinary air, which is about 7, so the polish you are paying for is also the thing most likely to fade. That is not a reason to avoid the stone – re-polishing is quick and cheap – but it is worth knowing that the surface is doing most of the work.

What you get

About 90% of this stone's face reads as brown, with a sparkle measuring roughly 2.24% of the face – above the middle of this tray, where the readings run from 1.21% to 3.37%. Buying it loose means you see the whole stone, including the base and sides a setting would hide, and you choose the metal and the maker yourself.

What has not been tested

Sunstone is usually untreated in general. This stone has no laboratory report and its treatment has not been tested, so that is the norm for the material rather than a finding about this piece.

Care and ordering

Warm water, mild soap and a soft cloth. Avoid ultrasonic cleaners and steam, which feldspar does not take well. One stone, sold once. Message us on WhatsApp for more photographs, and we deliver across Pakistan.

This particular stone

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

On the Mohs scale sunstone rates 6 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 sunstone 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 sunstone for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
