With perfect proportions and an ideal size, the round brilliant diamond fits perfectly as an engagement ring, as well as a pendant to enhance the charm of a necklace, a choker or even, to set a bracelet. Discover with us all the secrets and characteristics of the round diamond.
Characteristics of a round diamond
In the world of jewelry, it is possible to qualify the shape of a diamond as "cut". Thus, there are round, princess, oval, pear, heart, etc. sizes. However, this should not be confused with the term "cutting a diamond" which more commonly defines the act of "polishing" a rough diamond in order to give it sparkle and shine.
Concerning the brilliant-round cut, it is characterized by 58 facets, distributed between the pavilion, the rondiste and the crown of the diamond, with a typical ratio varying between 1,00 and 1,02. This cut, which naturally marries the crystal of the rough diamond, maximizes the brilliance and fire of the gemstone.
Although initially developed in Europe, this shape of diamond is considered the ideal American cut. This round shine is the most sought after in the industry, and many techniques have been implemented to double its shine and optimize its intensity.
How to recognize the ideal round diamond cut?
To maximize the brilliance of a diamond and optimize the quality of the cut, the diamond dealer must meet certain criteria relating to the proportions, dimensions and optical properties of each rough diamond.
Rough diamond is quite expensive and cutting can lose up to 70% of this raw material. To make his investment profitable, the diamond dealer will have the choice: either to keep the maximum weight of the cut diamond in order to minimize losses to the detriment of quality, or to cut the diamond while sacrificing a good part of its weight but guaranteeing much higher quality. Thus, it is possible to differentiate the various qualities of a round diamond by:
Ideal cut diamond: 1,00 carat with 55% to 70% loss in rough diamond
Very good size diamond: 1,10 carat with 50% to 65% loss in raw material
Good cut diamond: 1,20 carat with 45% to 65% loss in rough diamond.
The bottom line of all this is that a diamond of large proportions will not necessarily be of good quality. It is often preferable to opt for a stone with a lower carat but with an ideal size.
Perfectly cut round diamonds are also referred to as "Hearts & Arrows" or "H&A". These are stones of excellent quality and quite rare. When exposed to a special light, they reveal symmetrical patterns of arrows or hearts.
What is the price for a round diamond?
Cutting a round diamond involves a significant loss of raw material, its price is naturally quite high compared to other shapes (about 30% more than other sizes).
Of course, the price will vary from one jeweler to another, but also, the carat, the quality of the size, the purity, the color and the clarity of the precious stone. On average, a round diamond will cost:
Around € 1500 for a 0,5 carat diamond,
between 4500 and 6000 € for a 1,0 carat diamond,
between € 18-000 and up to € 21 for a 000 carat diamond.
The history of the round diamond
The first round diamond cut dates back to the 16th century and legend has it that it was the French Cardinal Mazarin its first designer by cutting a pendant in the shape of a cross. The earliest forms of brilliant diamond were therefore known as Mazarins.
Over time, more refined and complex techniques have emerged and the cutting of diamonds has undergone a great revolution. And so the Portuguese form "Peruzzi" or "old European cut" appeared around 1700.
It was not until 1919 that the ideal proportions of the round diamond were established by the mathematician Tolkowsky and this is how the modern round diamond came into being. By the way, at that time, the round cut was rather called the "Tolkowsky" shape. As for the criteria of quality and proportions, they are established by the GIA.
