The Light Keeper — 1ct Lab-Grown Diamond Pendant

The Light Keeper by Zanvari is a 1 carat lab-grown round brilliant diamond pendant, handcrafted in 925 sterling silver with rhodium plating, on an imported Italian box chain. Real diamond, grown rather than mined, graded by an independent laboratory, and made to order in Karachi by Zanvari, third generation jewellers since 1947.

Why a box chain?

A box chain is built from small square links, so it sits flat, does not twist, and is strong for its weight. It holds a one-carat pendant steady at the collarbone and wears well every day. The chain is imported from Italy, where box chain is a specialty, and finished to match the pendant.

What is a lab-grown diamond?

A lab-grown diamond is a real diamond. It is pure carbon in the same crystal structure as a mined diamond, with the same hardness (10 on the Mohs scale), the same brilliance, and the same grading scale — it is grown over weeks in a laboratory instead of over a billion years underground. A gemologist cannot tell the two apart by eye; only specialist equipment can. What changes is the price: a lab-grown stone costs a fraction of a mined one of the same grade, and comes with none of the mining.

Why silver, and not gold?

Because the stone is the point. A one-carat D-colour diamond in a heavy gold setting would more than double the price for metal that sits under the stone. Rhodium-plated 925 sterling silver gives the same white-gold look, keeps the budget in the diamond, and our lifetime replating guarantee means the finish stays white for as long as you own it. If you would prefer the same pendant in gold, ask us on WhatsApp for a quote.

Care instructions

Store in the Zanvari box when not wearing. Put the pendant on last, after perfume and lotion. Wipe with a soft microfibre cloth; a diamond can also be cleaned in warm water with a drop of mild soap and a soft brush. Rhodium plating will naturally wear with daily use — Zanvari's lifetime replating guarantee means this is never a concern.

Frequently asked questions

Are lab-grown diamonds real diamonds?

Yes. Chemically, physically and optically they are diamond — pure carbon, 10 on the Mohs scale, graded on the same colour and clarity scale as mined stones. The only difference is origin, which is disclosed on the laboratory report.

Is this the same as moissanite?

No. Moissanite is a different gemstone (silicon carbide) with more fire and a lower price; most of Zanvari's range is moissanite and we say so plainly on every page. The Light Keeper is diamond. If you want the look at a fraction of the price, our one-carat moissanite necklace is the honest alternative.

Does it pass a diamond tester?

Yes — it is diamond. A standard thermal tester reads it as diamond because it is; only specialist origin-testing equipment distinguishes lab-grown from mined.

How long does delivery take in Pakistan?

Set to order in 28–30 business days for diamond pieces — the diamond is sourced and imported to order — then a few days with the courier. We confirm the timeline when you order, with WhatsApp updates throughout. For enquiries, contact 0342 8269771.
