In Pakistan the name Jamunia is tied to the purple colour of the jamun fruit, and the stone has long been a familiar sight in jewellers' trays across the country. Many buyers choose it for its look, and some follow the Vedic tradition that links it with Saturn and wear it on an astrologer's advice.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 6.45 Carat. Its price is Rs. 4,500 — roughly Rs. 698 for each carat. Treatment: treatment not tested.

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 amethyst rates 7. It handles daily wear, but a hard knock can still nick an exposed corner, so a protective setting is a sensible choice. Clean it with warm soapy water and a soft brush, and keep it away from abrasive cleaners and high heat.

Whoever you buy amethyst 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.
