Evaluating a colored diamond relies on a complex body of knowledge involving human color vision, color memory and various methods of color classification, description, and communication. The subsequent task of arranging colors according to so-called “color grades”, adds yet another specialized dimension.

Experienced colored diamond collectors understand that grading laboratories' diamond reports or certifications only represent visual estimates of a diamond's color hue and strength. Therefore, the assigned “color grade” for an individual colored diamond represents a range of color, which may vary considerably. The variations could include noticeable differences in primary and secondary hues, lightness, and saturation.

A diamond color grading method that relies solely on visual color estimation is not necessarily repeatable and reproducible. This color estimation can also translate into errors in determining the quality, rarity, and ultimately the value of a colored diamond.

Our consultancy prides itself on delivering objective and meticulous color assessments to clients, in addition to relying on the visual evaluations and “color grades” of the world's leading laboratories. We go beyond visual inspection, and employ industry leading technology and techniques.

Our gemologist and consultant, Mr. Stephen Hofer, pioneered the use of color measurement instruments to the field of colored diamonds. We proudly extend Mr. Hofer's expertise with color measurement to thoroughly assess our clients' new acquisitions.

By consulting with Mr. Hofer prior to a purchase, the collector can accurately determine where a particular colored diamond falls within each color grade. This information enables even the inexperienced collector to add the right colored diamond to a treasured collection.
