Here is a 12.1 carat laser-cut amethyst, listed at Rs. 16,500 or about Rs. 1,364 per carat, one of the gentlest rates in this batch. Before you buy, check these points.

• Size: 12.1 carats is large; it reads as a statement ring or a full pendant.
• Colour: purple. On arrival, look for an even tone through the stone, and tilt it in daylight.
• Cut: laser cut; run a fingertip around the edge for chips.
• Hardness: Mohs 7, durable enough for a ring with sensible care.
• Heat: some amethyst is warmed to lighten it; ask us what we know about this stone.
• Reference: GS-000236.

At a rate this gentle, the real comparison is against other large amethysts: lay the colour of this one beside a few others and pick the purple that pleases your eye, because depth and evenness of tone separate good pieces from average ones. A weight over twelve carats also gives a jeweller room to work, whether you want a pendant or a broad ring.

The parcel is insured and tracked, and shipping is a flat Rs. 500 per order. Compare it with other pieces in the amethyst collection and give the care guide a read.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 12.1 Carat. Its price is Rs. 16,500 — roughly Rs. 1,364 for each carat. Treatment: treatment not tested. Quote reference GS-000236 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.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

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.
