Lab Grown Diamond Tennis Necklace 14K Gold

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.

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.

Every Agent Jewel diamond is lab grown and independently graded.

The first letter is colour — D is completely colourless, and the scale warms as it moves toward Z. The rest is clarity: VVS, VS and SI describe how many inclusions the stone holds. Everything we sell is eye-clean, meaning no inclusion is visible without magnification.
