Beyond the 4Cs

Diamonds come in every color of the rainbow. Except for very rare and fancy colors, the less color in a diamond, the more valuable it is.

Although many diamonds appear to have no body color at all, trace atomic elements other than carbon (C) may result in slight degrees of yellow, brown or gray body coloring. The color differences are often so slight that they are only detected by comparing them against a master set of laboratory-graded diamonds.

As a rule, color differences are measured by international grading scales created by either the American Gemological Society (AGS) or the Gemological Institute of America (GIA).

All Hearts On Fire diamonds are exclusively restricted to the top two color grades – the colorless and near colorless range.

Diamond Color Scale

Colorless
(D, E, F)

Example of a “colorless” diamond. This classification is rare and the most valuable. Hearts On Fire accepts diamonds in this color range.

Near Colorless
(G, H, I, J)

Example of a “near colorless” diamond. It takes a trained gemologist to see the difference between a “near colorless” and “colorless” diamond. Hearts On Fire accepts diamonds in this color range.

Faint Yellow
(K, L, M)

Example of a “faint yellow” diamond. The faint yellow cast of these diamonds is visible to the untrained eye. Hearts On Fire does not use diamonds of this color quality.

Very Light Yellow
(N, O, P, Q, R)

Example of a “very light yellow” diamond. The light yellow cast of these diamonds is readily visible to the untrained eye. Hearts On Fire does not use diamonds in this color range.

Light Yellow
(S, T, U, V, W, X, Y, Z)

Example of a “light yellow” diamond. Diamonds graded S through Z have a yellow cast that is obvious to the untrained eye. These diamonds would not qualify to be Hearts On Fire diamonds.
