Trilogy 2.25ct Engagement Ring in 18k yellow gold

Skydiamond is the world's first carbon-negative certified diamond. We have created the ultimate alternative, by alchemising the air we breathe into light-splintering British-made diamonds.

The first measure of a diamond’s quality is its size, measured in carats. A carat weighs one fifth of a gram or 0.2g.

Less is more when it comes to a diamond’s colour. A chemically pure and structurally perfect diamond has no colour at all. Skydiamonds are graded using AnchorCert’s scale going from D (colourless) to Z (light). Diamond colour is nearly impossible to discern with the naked eye and near colourless stones (G-J) offer superb value.

The purer the diamond, the higher its clarity rating. Clarity is determined by the nature, number, size and position of inclusions within a stone as well as any blemishes on its surface. Skydiamonds come in a wide selection of clarity ratings, which is reflected in the price.
