Size

Don’t know your size? Leave it on Adjustable. It opens and closes to fit 6 to 10, so there is nothing to guess.

Know your size? Pick the number instead — a fixed band sits cleaner and holds its shape longer.

If it does not fit, we resize it free — once, within 7 days of delivery. After that it is no longer free. Find your size →

The metal

It looks gold. It’s silver underneath.

This piece is solid 925 sterling silver with an 18K gold micron plating on top. Not gold-plated brass. Not gold-filled. Silver, all the way through — which is the metal that carries the BIS hallmark and the HUID number stamped inside.

Plating is a finish, and finishes wear. Ours is a micron layer, thicker than the flash plating most online silver carries, and with normal wear it holds for a long time. It will not hold forever, and anyone who tells you otherwise is selling you something.

The stone

Real colour. Cut in Jaipur.

A lab-grown diamond is a diamond. Same carbon, same crystal structure, same hardness — grown in a few weeks instead of a few billion years. It is in this piece because the design needed a white stone, and we do not use cubic zirconia at any price.

No two are the same. Including yours.

Every stone we set came out of the ground, so colour and character shift from one piece to the next. The stone that reaches you will not be identical to the one photographed here — a shade deeper, a shade cooler, an inclusion sitting somewhere no other stone has it.

That difference is the proof. Cubic zirconia is made to a formula, which is why a tray of it looks perfectly matched. Stones never do. If a seller promises you identical stones at a silver price, they are describing a formula, not a stone.

We cut and set this one for you. Nobody else has it, and we could not make it again if we tried. Which seems about right, given who it is for.

Check it yourself

Don’t take our word for it. Take the government’s.

Every Carat Hills piece carries a HUID stamped inside. Silver hallmarking is voluntary in India, so most silver sold online does not have one. Ours does, and you can check it without trusting us at all.

01

Download the BIS Care app. It is free, and it is the Bureau of Indian Standards’ own.

02

Find the six-character HUID stamped inside your piece and type it in.

03

You’ll see the purity grade, the testing centre, and the date it was hallmarked.

Before and after you buy

The details

Caring for a gold-plated finish

Take it off before bathing, swimming, workouts and sleeping, and keep it away from perfume, lotion and household cleaners. Wipe it with the cloth we send after wearing and store it in its pouch. The silver underneath tarnishes — that is normal and reversible, and it is one of the ways you can tell real silver from plated brass.

Skin safety

Our pieces are nickel-free. Nickel is the metal most people react to, and it isn’t in ours — which is why these are made to be worn every day, not saved for occasions. If you have a known metal sensitivity, tell us before you order and we’ll help you choose.

Shipping and exchanges

Free shipping across India on every order. Dispatched within three to five working days, delivered in five to eight. If something arrives damaged or faulty, tell us within seven days and we’ll replace it or refund you, and we pay the return shipping. Ring not fitting? Free resizing, once per order, within seven days. We don’t take change-of-mind returns. Full policy →

What comes in the box

Your piece arrives in a Carat Hills box with a polishing cloth, a care card, and a Stone Story card telling you where your stone came from and what makes it different from the next one.
