Technology Overview

The 4Cs

The diamond grading has to distinguish key diamond features accurately. Its basis so far has consisted of 4 Cs: carat weight, cut, clarity, and color.

The current challenge

Confusingly, diamonds that are identical in terms of 4Cs can look and be priced quite differently. This is why professionals and consumers often look for diamond beauty clues beyond the 4 Cs.

Optical Performance Evaluation

Fire

Fire is colored flashes that we see in colorless diamonds. Observed Fire depends on the colored flashes quantity, size, duration, brightness, saturation, and distribution.

Optical Performance Evaluation

Brilliance

Diamond brilliance is an optical illusion: the perceived brightness of the object significantly exceeds its actual brightness. It occurs when several parts of the object with different brightness are observed within a single space-time domain.

In the case of a diamond, these parts are its virtual facets. Two virtual facets belong to the same space-time domain when an observer cannot separate them due to spatial or temporal limitations of the sense of vision.

Optical Performance Evaluation

Optical Symmetry

Optical symmetry shows diamond symmetry grade when viewed face up. A score is calculated from crown (ASET) image for fancy shapes and crown (ASET) and pavilion (Hearts) images for round shapes.

Face-up fluorescence

A face-up fluorescence score shows the percentage of diamond area that belongs to different fluorescence grades for the diamond image taken face up in UV 385nm light.

Optical Performance Evaluation

Spread

Diamonds of the same weight can have different apparent sizes depending on their geometry. This visual size is described in terms of spread characteristics. Positive spread means that a diamond looks larger than Tolkowsky round with the same weight, negative means the opposite
