Different shapes of diamonds | I-diamants

There are many forms of cut diamond. We distinguish the size of the round brilliant sizes called "fantasy", such as princess cut, emerald, oval ... and many others. The shape of the brilliant round is undoubtedly the most accomplished, the one whose study of the optimal proportions has been the most thorough. It is also the most classic, the most universal, carrying in it all the symbolism associated with the round shape. "Fancy" sizes are generally less expensive than round sizes, which are more difficult to evaluate. The quality of the proportions and size will greatly influence the price.
The choice of cut diamond shape is usually determined by the shape of the original rough diamond and the position of the inclusions. We will below present each of the main forms. The preference for one over the other is very personal: it is a purely aesthetic choice. But it also depends on the style of jewel desired. In addition to the shape, you must consider other criteria when choosing a diamond: size, purity, weight or color.

Les différentes formes d'un diamant


Round brilliant cut diamonds

With an absolutely perfect and timeless aesthetic, round brilliant cut remains the safe bet. Calibrated in 1919 by Marcel Tolkowsky to give it maximum brilliance and brilliance, the stone has 57 facets. This form has remained since the most requested because it is the most brilliant. Certificates from GIA, HRD and IGI laboratories (the three most famous) note all its size parameters. Ratings range from Fair to Excellent. We recommend diamonds with size ratings of either Very Good or Excellent.

Princess cut diamonds

The princess is particularly suited to architectural jewelry with clean lines. It is a square or rectangular size, with generally 76 facets that ensure a strong flicker. A princess cut is smaller and less expensive than a brilliant round of equal weight. The width of the table requires good purity. For princesses, we recommend that you focus on IF-VVS-VS purities and avoid SI1-SI2 and Stitched.

Emerald cut diamonds 

Originally, it was reserved for emerald stones, from which it takes its name. The Emerald size gives a translucent light, unique in its kind. It is a distinguished size, sober but very "classy". Requires diamonds of good purity: the table is important and the slightest defect becomes visible. This is why the emerald diamond must be pure or VVS-VS. At worst SI1, but then it is imperative that the inclusions are on the side.

Pear shape cut diamonds

A drop of water of 58 facets, often worn as a pendant, which is as much of the round size as the marquise with its rounded and pointed edges. The pear shape is by far the most difficult to choose because the most rarely cut. It is indeed very difficult to find the right compromise between its length and its width. But a beautiful pear-shaped diamond is a marvel of nature and human work.

Oval cut diamonds

The 56 facets of the oval cut give a resolutely modern form that combines the classicism of the round brilliant and the elegant femininity of the more elongated forms like those of the marquise and the pear. Often set in diamond center on solitaires or rings, the oval diamond can also be set with surrounding stones. There are also beautiful wedding rings of oval diamonds.

Cushion cut diamonds

The cushion diamond is a very trendy form nowadays because jewelery brands have used it a lot in their creations in recent years. Very elegant and very brilliant, it is a good alternative to round diamonds, even if its brilliance remains nevertheless less than that of round brilliant diamond. The ideal is to crimp it on a ring with brilliant round diamonds around to enhance its brilliance.
