Is the diamond in this ring real and certified?

Yes. The centre stone is a lab grown diamond - chemically and optically identical to a mined diamond. A certificate of authenticity is provided with every order.

What metal is this ring made from?

18k gold vermeil - a 5 micron layer of 18k gold bonded over a 925 sterling silver base. The surface is genuine 18k gold, but the underlying metal is sterling silver, not solid gold.

What is the return policy for this ring?

GemHub accepts returns within 30 days of delivery for unworn items in original condition with the packaging, authenticity certificate and intact tags. Made-to-order, custom, engraved, resized or personalised pieces are non-returnable. Email care@gemhub.in to confirm eligibility for your order.

Diameter and circumference are inside measurements of the ring. Indian sizes 11 and 18 sit between two US sizes, so no US size is shown for them.

How to find your size

You have a ring that fits

Lay it on a ruler and measure the inside diameter from inner edge to inner edge in millimetres. Find that number in the Diameter column.

No ring to hand

Wrap a thin strip of paper or a piece of string snugly around the base of your finger, mark where it overlaps, then measure that length in millimetres. Find it in the Circumference column.

Tips for a good fit

Measure at the end of the day, when your fingers are at their largest.
The ring must pass over the knuckle: measure the knuckle as well and choose a size between the two.
Wide bands (6 mm and above) fit more snugly, so go half a size up.
Between two sizes? Choose the larger one.

Still unsure? Send us a photo of your ring on a ruler and we will confirm the size for you.
