Why choose a black diamond ring

A black diamond ring is bold, modern and unmistakably different. Deep and opaque where a colourless diamond is bright and clear, a black diamond engagement ring makes a confident statement and has become one of the most popular alternative choices for couples who want something striking. Its popularity took off when Carrie Bradshaw was given a black diamond engagement ring in Sex and the City, and it has been a favourite for unconventional, contemporary rings ever since, in both women's and men's designs.

The most famous black diamonds

The most storied black diamond is the Black Orlov, also called the Eye of Brahma, a 67.5 carat stone said to have been prised from a temple statue in India and rumoured to be cursed, a legend it was eventually recut to try to break. The Spirit of de Grisogono, at over 312 carats, is the largest cut black diamond in the world, and the 88 carat Korloff Noir is said to bring good luck to anyone who touches it, the opposite of the Orlov's reputation.

Black diamonds were long considered fit only for industrial use until designers began setting them in jewellery, contrasting them with colourless stones. These famous stones are natural, but they are why black carries such drama, and that colour is now available as a lab grown stone.

What gives a black diamond its colour

A black diamond's colour comes from inclusions rather than a trace element. Large numbers of tiny dark inclusions, often graphite, are scattered through the stone, and they absorb light so completely that the diamond appears opaque black with a metallic lustre. Because the colour comes from these inclusions, a black diamond is prized for the depth and evenness of its surface rather than for internal sparkle. The same effect is achieved in a lab grown black diamond.

Why lab grown makes sense for black

A lab grown black diamond gives you that deep, even colour and the hardness that makes diamond the toughest of all gemstones, with a clear and traceable origin and strong value. Because it is so hard wearing it suits everyday use well, which makes it an ideal choice for a dramatic, modern ring that will stand up to daily life. Lab grown diamonds are created in advanced laboratories using the same processes that form diamonds within the earth. The result is a real diamond, with the same chemical, physical and optical properties as a mined stone, the only difference being its origin. Each diamond is grown under controlled conditions, which makes it fully traceable and conflict free, and removes the environmental impact of mining.

Choosing the shape and setting

Round and cushion cuts give a classic outline, while emerald and princess cuts suit a more architectural, contemporary look. The dramatic colour is at its boldest against white metals, where the contrast between bright metal and deep stone is sharpest, which is why so many black diamond ring designs use platinum or white gold. A halo of colourless diamonds creates a striking light and dark contrast, while a plain solitaire makes the strongest single statement. A black diamond eternity or wedding ring carries the colour through the set.
