Everything you need to know about diamond cutting

The size of the diamond is often considered the most determining factor in the beauty of a stone. Contrary to popular belief, it does not correspond to the shape, but to the way in which the diamond is cut to interact with light. Successful cutting allows the stone to reflect, refract and disperse light optimally, revealing its radiance, brilliance and fire.

Among the 4c diamond, size is the only characteristic directly influenced by human know-how. It transforms a rough diamond into a cut diamond capable of enhancing a ring, earrings or any other piece of jewelry. This is why the diamond cut plays an essential role in the choice of a stone intended to accompany the important moments of life.

Distinction between shape and size quality

It is essential to distinguish the shape of the diamond from the quality of its cut. The shape designates the exterior silhouette of the stone: round, princess, pear, fancy... The cut, for its part, evaluates the precision of the facets, their angles, their symmetry and their polishing.

Thus, two diamonds of the same shape can present a very different result depending on the quality of their cut. An attractive shape is not enough: only a controlled size allows light to circulate harmoniously inside the stone.

The influence of cutting on the fire and luster of the stone

When light enters a diamond, it reflects off the internal facets before exiting through the table. A well-proportioned diamond cut maximizes this phenomenon, creating intense fire (color dispersion) and dazzling shine. Conversely, poor pruning lets light escape from the sides or bottom, dulling the overall appearance.

It is this subtle interaction between light and facets that explains why two stones of the same weight and same color can offer a radically different visual result.

The diversity of shapes makes it possible to adapt the diamond to each style, each genre and each jewelry use.

The round brilliant diamond: the absolute reference

The round diamond today represents the majority of global sales. Its brilliant size, designed to optimize the return of light, offers an intense and perfectly balanced shine. This iconic shape has established itself as a reference in jewelry thanks to its ability to fully reveal the natural brilliance of the diamond.

Versatile and timeless, the round diamond naturally finds its place in a solitaire ring, where the stone becomes the purest expression of jewelry know-how. This approach, based on the enhancement of size and light, is found in particular in emblematic creations of the House, such as the Solitaire Amoretto Brillant, designed to reveal all the precision and harmony of a perfectly cut round diamond.

Rectangular and square sizes: Princess, Emerald and Asscher

The princess cut is distinguished by its modern and angular brilliance, while the emerald cut and Asscher favor stepped facets, revealing the purity and inclusions of the stone. These shapes seduce with their graphic elegance and their architectural character.

Elongated shapes: Marquise, Pear and Oval

Elongated shapes, such as the pear or the oval, offer an impression of size that is often greater than the actual diamond carat. Their slender silhouette captures the light subtly and visually elongates the finger, while maintaining a refined balance between elegance and presence. These shapes seduce with their ability to combine character and softness, while highlighting the line of the hand.

This aesthetic is deployed aptly in creations that emphasize the verticality of the stone. The pear shape, in particular, reveals all its singularity in pieces like the Eboris Twin pendant or the Eboris Twin earrings, where the precision of the cut highlights the purity of the diamond. It is also expressed forcefully in the rings of the Eboris collection, designed to magnify the elongated shape of the stone and reveal all its elegance, whether it is a piece of jewelry with character or a piece intended to mark an essential moment.

Niche sizes: Heart and Cushion

The cushion cut, recognizable by its rounded contours and its slightly retro appearance, seduces with its timeless charm and soft elegance. It evokes vintage-inspired jewelry, where light diffuses subtly through generous facets. The heart shape, rarer, is aimed at those looking for strong symbolism, intimately linked to emotion and attachment.

These fancy sizes are often chosen for very personal creations, such as birth jewelry or pieces designed to mark a moment in life. This particular sensitivity is found in particular in the Solitaire Amoretto Cushion, designed to highlight the softness of the lines and the luminous depth specific to this singular shape.

Choosing a diamond is above all a search for balance. The cut plays a central role in the perception of the stone, revealing its brilliance, its personality and its overall harmony. More than an isolated criterion, it is part of a global reflection where proportions, light and elegance interact subtly.

Finding the balance between vibrancy and proportion

Depending on the characteristics of the stone, certain sizes offer a remarkable luminous expression while preserving great visual elegance. A Very Good size, for example, can present a particularly balanced result, revealing light with finesse and naturalness. The main thing lies in the consistency of the proportions, much more than in the search for a few extra hundredths of a carat.

The size is always assessed in relation to the other characteristics of the stone. The color of diamonds, just like the carat diamond, influences the overall perception of brightness and visual balance. It is the harmony between these criteria that allows a diamond to fully reveal its personality and express all its natural beauty.
