The Monique Round Lab Grown Diamond Ring

Carat is a measure of weight, not size — though the two move together.

ctw means total carat weight: the combined weight of every stone in the piece. All of our diamonds are lab grown and graded F colour, VS clarity.

All Agent Jewel pieces are made in solid gold or platinum — never plated, never filled.

14K gold is 58.5% pure gold. It is harder and more scratch-resistant than 18K, which makes it the everyday choice for rings and bracelets.

18K gold is 75% pure gold. The colour is richer and warmer, and it carries a higher intrinsic value.

Platinum is naturally white and hypoallergenic, so it never needs re-plating. It is the densest and most durable of the three.

Not sure of your size? Measure a ring you already wear: the inside diameter in millimetres maps directly to a US size.

If you are between sizes, size up — fingers swell slightly through the day and in warm weather.
