Their rarity and exceptional brilliance make them a fascinating choice for buyers seeking something truly unique.

Choosing the right diamond shape ultimately comes down to personal preference, but there are several factors worth considering before making your decision.

Sparkle

If maximum brilliance is your priority, round brilliant, oval, radiant and princess cut diamonds are among the best performers.

Size Appearance

Some shapes appear larger than others at the same carat weight. Oval, marquise, pear and elongated cushion cuts typically offer a larger face-up appearance.

Style

Round, oval and cushion cuts offer timeless appeal, while emerald and Asscher cuts provide a more sophisticated, architectural look. Heart, marquise and moval cuts can offer something more distinctive.

Budget

Fancy shapes are often more affordable than round brilliant diamonds, allowing buyers to maximise carat weight without increasing budget.

Durability

Shapes with pointed corners or tips, such as princess, pear, marquise and heart cuts, may require more protective settings than shapes with rounded edges.

While classic shapes remain popular, buyer preferences continue to evolve.

Oval Cut Diamonds

Oval diamonds remain one of the most sought-after shapes thanks to their exceptional sparkle, elegant silhouette and larger face-up appearance.

Elongated Cushion Diamonds

Elongated cushions continue to grow in popularity, combining soft rounded corners with a larger-looking shape and romantic appeal.

Radiant Cut Diamonds

Radiant cuts are increasingly popular among buyers seeking maximum sparkle in a modern rectangular shape.

Moval Diamonds

A hybrid of oval and marquise cuts, moval diamonds are one of the fastest-growing shape trends thanks to their distinctive appearance and elongated proportions.

Old Mine Inspired Cuts

Vintage-inspired cushion cuts featuring chunkier facets and antique character have seen growing demand among buyers looking for something unique.
