  • The real effect on the finger, explained

Nine shapes, explained without jargon

Round brilliant

Maximum fire thanks to 57 calculated facets. The most chosen shape and the easiest to resell.

The most expensive per carat: it wastes more rough.

Oval

Visually elongates the finger and looks 10 to 15% larger than a round of the same weight.

Roughly 20% less than an equivalent round.

Cushion

Softened corners and warm sparkle, very photogenic as a halo or a solitaire.

Excellent visible-size-to-price ratio.

Pear

A signature silhouette, confident without being showy. Slims the hand when the point faces the nail.

Often 25 to 30% below a round of the same weight.

Marquise

The shape that looks largest at equal weight: its visible surface is the greatest.

Among the best values per carat.

Radiant

Architectural lines and intense brilliance: the compromise between round sparkle and emerald geometry.

A good balance of presence and budget.

Emerald

A sober hall-of-mirrors effect, high fashion. Needs good clarity, since inclusions show.

Good value per carat, but demands a higher clarity grade.

Princess

Square, modern, lively sparkle. The corners benefit from a protective setting.

Often 20 to 25% below an equivalent round.

Heart

The most romantic and the rarest. It needs perfect symmetry to read clearly.

Variable: cut quality drives the entire price.

How to decide in three questions

  1. Which rings does she already admire?

    Look at her current jewellery and what she saves online. The shape is almost always visible there.

  2. Does she want volume or line?

    Oval, marquise and pear elongate the hand. Round, cushion and princess concentrate the sparkle.

  3. What effect day to day?

    A point or corners need a protective setting if she works with her hands.
