Aquamarine, called Beruj in Urdu, takes its name from sea water, and the colour of this 12.45 carat stone fits it: a soft sea blue. It is a natural stone, offered here at Rs. 5,030.

That price is about Rs. 404 per carat, a figure worth keeping in mind because aquamarine is usually priced by the carat and the rate shifts with colour and size. Reference GS-000257.

How it wears

Mohs hardness runs from 7.5 to 8, which is a good level for rings. It is tougher than amethyst, so everyday wear is realistic. Clean it with warm soapy water and a soft brush, and keep it away from hard knocks.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 12.45 Carat. Its price is Rs. 5,030 — roughly Rs. 404 for each carat. Treatment: treatment not tested. Quote reference GS-000257 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 aquamarine rates 7.5 to 8. 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.
