A pendant is the easiest piece of gemstone jewellery to get right, which is why it is usually the best first purchase. There is no finger size to measure, no resizing later, and nothing to catch on clothing. For aquamarine it has a further advantage: a pendant hangs where daylight reaches it, and daylight is where this gem looks its best.

The stone

15.25 carats, which is 16.76 ratti. Shape: drop — recorded for this individual stone, not assumed. Origin: Afghanistan. Rs. 11,250, about Rs. 738 per carat, reference GS-000278.

Why a drop is made for this job

• It has a natural top. The point takes the bail, so the stone hangs correctly without a workaround.
• The broad end catches light. As you move, the widest part of the stone swings into the light — which is what you want from a pale blue.
• It suits a fine chain. At 15.25 carats it is substantial enough to be seen and light enough that a delicate chain carries it without sagging.
• It is hard to use elsewhere. In a ring a point snags; in earrings it needs a matched partner. A pendant is where a drop belongs.

Specifying the pendant

Ask for an open back. It is the single most useful instruction for a pale stone — light entering from behind lifts the blue, while a closed back makes the same stone look grey and flat. A bezel with an integrated bail is the cleanest and most secure option; claws let in more light from the sides but need checking once a year. White metal — 925 silver or white gold — keeps the blue cool and clean, where yellow gold warms it towards green. A 16 to 18 inch chain sits at the collarbone and suits a single stone.

Can you set it for me?

Yes. Message us on WhatsApp at +92 308 887 3888 with the style you want and we will quote the mount separately from the stone, so the two prices stay visible rather than being rolled into one figure.

Measurements

Length and width have not been recorded for this piece. These matter more on a drop than on most shapes, because the bail and the outline have to work together, so ask us to measure it before your jeweller starts.

Treatment and origin

Aquamarine is commonly heated to remove green tones and leave a purer blue — standard, stable and accepted. We have not tested this stone, so the specification reads "treatment not tested". Origin is recorded as Afghanistan, which is where most of the aquamarine reaching Pakistani dealers comes from; treat that as what our records state rather than a laboratory finding, since no routine report names a country for this gem.

Durability

Beryl is 7.5 to 8 on the Mohs scale. A pendant leads an easier life than a ring, so wear is rarely an issue. Warm soapy water and a soft brush; avoid steam and ultrasonic cleaners.

Ordering

One piece only. Flat Rs. 500 delivery anywhere in Pakistan, insured and tracked, dispatched in one to two working days. Cash on Delivery, seven days to return it unused. More pendant-sized stones in the aquamarine collection.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 15.25 Carat. Its price is Rs. 11,250 — roughly Rs. 738 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference GS-000278 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, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
