Laboratory-grown diamonds & coloured gemstones · Gurugram

Designed with you.Made for you.

Casablanca is a small jewellery studio in Gurugram run by Jyotsna W. There is no catalogue. You tell us what you want, we sketch it together, and a karigar makes it by hand in laboratory-grown diamonds or natural coloured stones. Every piece is hallmarked, certified on request, and ours to look after for as long as you own it.

The collection.

Nothing here is in stock. The gemstone and polki pieces are ours, photographed as they were made for their owners, and can be remade around your stones. The laboratory-grown pieces are made to order in 15–21 working days.

Most families have gold sitting in a locker that nobody wears. Bring it to us. We weigh it in front of you, agree a design, melt it down and remake it, set with laboratory-grown diamonds if you like. The value of your gold comes off the price.

How it works

It starts with a conversation.

Nothing here is stocked. Each piece is worked out between you, Jyotsna and the karigar who will make it. This is how that usually goes.

First

We talk

What it’s for, roughly what you’d like to spend, whether you want a diamond or a coloured stone, and the metal you actually wear. At the studio over chai, at your home in NCR, or on a video call.

Then

We sketch and pick stones

You’ll see loose stones under a loupe and a pencil sketch of the piece. Nothing is cast until you’re happy with both.

Finally

We make it and bring it to you

made by hand and hallmarked; certification on request. Jyotsna delivers in Delhi NCR herself; elsewhere in India it comes by insured courier.

“A shop sells you what’s in the case. I’d rather make the one piece you actually want, and then be the person you call if the clasp ever sticks.”

What comes with every piece

The paperwork, and the promises.

Hallmarking & certification
Every piece is hallmarked. A stone or metal certificate is available on request; tell us when you order and we arrange it.
IGI certificate
Any centre stone of 0.30 ct or more comes with an IGI report, its number laser-inscribed on the girdle. The report says how the stone was grown.
Made to last
Every piece is made by hand to your measurements, and we are always here for resizing, repairs and redesigns for as long as you own it.
Looked after
Bring it in once a year and we’ll clean it and check the prongs, free. Resizing in the first year is free too.

We say laboratory-grown diamond in full because that is what Indian Standard IS 19469:2025 asks for. Ours are grown by CVD or HPHT, and we’ll tell you which. The coloured stones and polki are natural; a laboratory report is available on request.

From the designer

It started with pieces for friends.

I began with coloured stones — rubies, emeralds, tourmaline, polki — made the way the old Delhi workshops make them, for friends who wanted something they couldn’t find in a shop. The diamonds came later. A friend wanted a two-carat stone and had been told, kindly, that she couldn’t afford one. A laboratory-grown stone got her the ring she wanted, and word went round the way it does in Delhi.

That is still how Casablanca works. One conversation at a time, one piece at a time, made by the same karigar. I don’t keep a catalogue and I won’t push you. If a piece isn’t right, we don’t make it.

— Jyotsna W.

Absolutely loved the ring! My mom gifted me this beautiful lab-grown diamond ring from Jyotsna and I couldn’t be happier. The design is elegant, the sparkle is gorgeous and the finishing is just perfect. It’s even more special because it’s a gift from my mom. Thank you, Jyotsna, for such a beautiful piece of jewellery!
