About Round cut lab-grown diamonds

The round brilliant is the most popular cut — 57 facets engineered for maximum light return and the widest choice of sizes. The round cut has its own character, so cut quality, proportions and — where relevant — length-to-width ratio matter as much as the 4Cs when you choose a stone.

Every diamond here is lab-grown — a real diamond with the same carbon crystal structure, hardness and fire as a mined stone, created above ground in a matter of weeks rather than extracted over millennia. Because origin is the only difference, you typically pay 60–80% less than the mined equivalent for the same look, and every stone is conflict-free and traceable.

How to choose a round diamond

• Cut & symmetry first — this is what makes a diamond sparkle; prioritise it over a slightly higher colour or clarity grade.
• Colour — G–H (near-colourless) faces up white to the eye in most settings; D–F is the top colourless tier.
• Clarity — VS and better is eye-clean; VVS shows nothing even under a loupe.
• Ratio & outline — compare a few round stones side by side to find the silhouette you prefer.

Each stone is independently certified by IGI or GIA, hand-inspected and photographed by our team in Sweden before dispatch, and shipped fully insured with free delivery and 30-day returns. Every diamond is one of a kind — the exact stone you see is the stone you receive, ready to wear loose or set into a ring with help from our gemologists.
