Without the precision and perfection of the cut a diamond can lose large part of its beauty. The “allure” of a natural diamond relies, more than anything else, on the quality of the cut.
The cut of every diamond has three attributes that are extremely difficult to analyze and quantify:
•Brilliance is the total reflected light
•Fire is the dispersion of light in the colors of the spectrum
•Scintillation is the flash of light or “sparkle” that appears when moving the diamond.
In a perfectly cut diamond the light that comes into the stone is reflected on the viewer creating a beautiful prismatic game and a bright white sparkle in the color of the iris.
Three factors are considered to determine the value of a diamond from the quality of the cut: proportions, symmetry and polish.
In early 2005, after 15 years of intense research and tests, the GIA established the Diamond Cut Grading System for brilliant round-cut diamonds in the color scale from D to Z, with “excellent” to “poor” grades.
GIA CUT SCALE: EXCELLENT | VERY GOOD | GOOD | FAIR | POOR
Diamonds that have one, two or three “Very Good” characteristics see their price reduce from 5 to 15% compared to Excellent. One single Good characteristic can reduce the price by another 10%. There is a 35% difference in price between a Triple Good and a Triple Excellent.
Diamond Love Bond exclusively sells diamonds that have qualified as excellent in all three of the quality conditions. For the first time in Italy we also offer diamonds with Rapaport IDC – Investment Diamond Certificate.
This new certificate can only be given to brilliant round-cut natural diamonds that already received a gemological certificate by the GIA – Gemological Institute of America in the last two years (excluding all other gemological certificates such as HRD, IGI), that have Triple Excellent quality characteristics (excluding diamonds that have very-good, fair, poor quality), no fluorescence (excluding Faint, Medium, Strong, Very Strong fluorescence) and have rigid measurement parameters.
