Forty-four carats of aquamarine is a lot of stone, closer to a small pebble of sea glass than a conventional ring centre. It is a natural aquamarine (beruj) of 44.75 carats, noted as sea blue, and it needs a purpose before you buy it.

The price is Rs. 37,500, which works out to about Rs. 838 per carat; the reference is GS-000282. Heat is a routine step for aquamarine, used to lose green tones, so please ask on WhatsApp +92 308 887 3888 about this particular stone, and independent lab testing is available on request.

A weight like this belongs in a pendant, a brooch-style piece or a bold cocktail-sized ring, where its size is the point. At 7.5 to 8 on Mohs it is tough, but a stone this big stands proud and can be knocked, so a deep setting helps. A custom silver ring setting can be discussed on WhatsApp.

Clean it gently with soapy water and store it in a pouch of its own. The aquamarine category lists smaller options if this is more than you need, and delivery is by insured, tracked courier.

Cash on Delivery is available across Pakistan, so you inspect the stone before paying, and returns are accepted within 7 days of delivery. Before you choose, read our aquamarine guide.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 44.75 Carat. Its price is Rs. 37,500 — roughly Rs. 838 for each carat. Treatment: treatment not tested. Quote reference GS-000282 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.
