Το Diamond Color βαθμολογείται ως προς το πόσο λευκό ή άχρωμο είναι ένα διαμάντι. Η GIA βαθμολογεί τα διαμάντια από το D έως το Z, με το D να είναι το πιο άχρωμο, και Z που περιέχει αισθητή καφέ ή κίτρινη απόχρωση.
Η τιμολόγηση των διαμαντιών συνήθως αντικατοπτρίζει αυτούς τους βαθμούς — μερικές φορές σημαντικά. Στις περισσότερες περιπτώσεις, the naked eye cannot tell the difference between two adjacent color graded diamonds, though the price difference may be significant.
The most critical aspect with Color is to determine if it appears colorless in relation to its setting. You also want to be certain that a diamond is clear of any tinting that takes away or interferes with white and colored light reflections. The K Color in this Cushion Cut Diamond, για παράδειγμα, distracts from the sparkle of the diamond while this I Color Diamond is radiant.
Λαμπρότητα, or sparkle, is created from the way the diamond is cut. It is not advantageous to purchase a diamond that distracts from this important principal characteristic.
As a general recommendation, review each diamond closely and ask for the assistance of an expert. This is the best way to ensure you’re not paying for a feature (i.e. too high of Color grade) that will go unnoticed, or purchasing a diamond that distracts or interferes with light reflection.
Σημείωμα: Certain colored diamonds are valued stones, like a fancy pink or green diamond. Color grades for these diamonds are distinctly different than traditional “white” diamonds.
