Natural or lab-grown
Neither is better. It comes down to what matters most to you.
Natural diamonds
Valued for geological rarity, formed in the earth over billions of years.
Lab-grown diamonds
The same physical, chemical and optical properties, at a lower price, so the budget goes further on size or quality.
Styles
Every style is available in platinum and white, yellow or rose gold.
Solitaire
One diamond on four or six claws. Nothing competes with the stone.
Halo
A ring of small diamonds around the centre adds presence and apparent size.
Hidden halo
Small diamonds set beneath the centre stone, adding sparkle from the side.
Cathedral
The shoulders rise to support the centre stone.
Three-stone
A centre diamond flanked by two smaller stones.
Bezel
A fine rim of metal around the stone. The most protective setting.
What to look for
Visual performance first
Two diamonds with the same report can look very different. We compare them side by side.
The four CsChoose the shape
Round is the most brilliant. Oval and pear look larger for their weight.
Diamond shapesMatch the metal
White metals suit colourless stones. Yellow gold flatters warmer grades.
