Nearly forty-five carats of aquamarine is a lot of stone, closer to a small piece of sea glass than to a normal ring centre. This natural beruj weighs 44.75 carats, it is sea blue, and you should have a use in mind before you buy it.

The reference is AG-000282. Heating is a routine step with aquamarine, used to remove green tones, so please ask us on WhatsApp about this particular stone. An independent lab test is your option.

A stone this heavy belongs in a pendant, a brooch-style piece or a bold cocktail ring, where size is the whole point. At 7.5 to 8 on the Mohs scale it is tough, but it will stand proud and can be knocked, so a deep setting helps. We can discuss a custom silver ring setting on WhatsApp.

Clean it gently with soapy water and store it in its own pouch. If this is more than you need, the aquamarine category has smaller options. It travels by insured, tracked courier.

Pay on delivery after a proper look; Karachi usually gets it in 1–2 working days, other cities in 2–4, and returns are open for 7 days. Read our aquamarine guide before you choose.
