Keep the numbers 7.5 to 8 in mind with aquamarine. That is its Mohs hardness, and it means the stone resists everyday scratches far better than pearl, opal or lapis, which makes it a sensible choice for a ring worn often. A sharp blow can still chip any gem, so a protective setting matters.

This is a natural aquamarine (beruj) from Afghanistan, 24.9 carats, sea blue, under reference AG-000283. Many aquamarines are heated to remove green and deepen the blue; for this particular stone, ask us on WhatsApp.

The weight suits a pendant or a broad statement ring. Silver keeps the look cool and clean, and we can talk through a custom silver ring setting with you on WhatsApp.

To care for it, rinse it in warm soapy water, brush gently behind the stone and dry it with a soft cloth. Keep it in its own pouch. An independent lab test is your choice. If you are weighing options, browse the aquamarines, or read our gemstone care guide.

Inspect it at your door before paying; Karachi usually gets orders in 1–2 working days, other cities in 2–4, and returns run for 7 days.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 24.9 Carat. Its price is Rs. 21,000 — roughly Rs. 843 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference AG-000283 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.

Whoever you buy aquamarine 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. We check every aquamarine for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome.
