Round Brilliant diamond
Absolutely perfect and timeless aesthetics, the round brilliant cut remains the sure value. Calibrated in 1919 by Marcel Tolkowsky to give it maximum brilliance and shine, the stone has 57 facets. This shape has remained the most sought-after since then because it is the most brilliant. The certificates of the GIA, HRD and IGI laboratories (the three most reputable) note all its size parameters. Ratings range from Fair (Poor) to Excellent. We recommend diamonds with either Very Good or Excellent cut ratings.
G or Extra White (formerly called "Top Wesselton")
As with F, the color of the stone is extremely faint and only perceptible from a certain angle by an expert. It is the first quality sold in beautiful traditional jewelry stores. To the naked eye, these diamonds appear colorless once cut and mounted on a piece of jewelry.
Very Small inclusion(s)
Difficult to find with a 10X magnifying glass. Position and number determine the difference between VS1 and VS2. Require a recognized certificate.
Diamond Cut Grade
Diamond cut grade is a measure of how well a diamond's facets are cut and polished, impacting its brightness, brilliance, and fire.
The diamond is a light accumulator. When a diamond is cut according to good proportions, qualified as cut grade, the light remains imprisoned and reflects itself from one facet to the next, exploiting the diamond’s refraction property to the maximum, and it then comes out again through the top (the table). A diamond that deviates from the ideal proportions lets part of the light escape through its table.
The proportions defined by the cut grade determine the fire and the brightness (light return), the scintillation of the diamond. It is the most important criteria. The finish grade qualifies the divergences in the symmetry of the diamond cut shape, the facets and the quality of the polish.
These criteria are often ignored. We attach the greatest importance to them: all our diamonds are exclusively “excellent”, “very good” or “good”. Diamonds of a “medium” or “bad” quality convey the choice of favouring weight instead of the quality of the diamond cut.
Excellent Cut
Top-of-the-line cut, exhibiting optimal brilliance and sparkle.
Diamond Polish Grade
Diamond polish grade refers to the smoothness of a diamond's surface and the absence of surface blemishes, which affects its light interaction and brilliance.
Excellent Polish
No polish flaws are visible under 10x magnification, resulting in the best sparkle and brilliance.Diamond Symmetry Grade
Diamond symmetry grades assess how precisely a diamond's facets are aligned and proportioned.
