Each diamond is completely unique and has individual characteristics — even those that are subtle — which can impact its visual appeal and value.


A reliable gemological report can provide a clear basis for comparison

 

Clarity Grade

Flawless (FL): No visible inclusions or surface blemishes at 10x magnification.

Internally Flawless (IF): No visible internal characteristics at 10x magnification, but may have minor surface blemishes.

Very Very Slightly Included (VVS): With very, very small inclusions that are difficult to see at 10x magnification.

Very Slightly Included (VS): With very small inclusions that are difficult to somewhat easy to see at 10x magnification.

Slightly Included (SI): With small inclusions that are easy or very easy to see at 10x magnification. Occasionally, visible to the unaided eye.

Included (I): With medium or large inclusions that are obvious to the unaided eye.

 

COLOR GRADE

For colorless to light diamonds, color is graded on a scale from “D” (colorless) to “Z” (possessing a strong tonal modifier). Most diamonds have a yellow or brown tonal modifier.

 

Cut (Shape and Style)

Cut describes the silhouette or form created by a diamond’s contours and facets. Shapes vary from round to fancy cuts, such as emerald, pear, and princess. Style includes variations of brilliant, stepped, and mixed cuts. Beautiful diamonds can be found in virtually any shape or style.
Some preferred stones achieve a particularly precise and romantic “hearts & arrows” pattern that reveals a circle of hearts through the pavilion and arrows through the crown.

Finish

Finish refers to the analysis of a diamond’s polish and symmetry. Polish relates directly to the smoothness and overall surface condition of the diamond. Symmetry relates to facet shape and arrangement, and the overall exactness of the stone’s contour and outline. Both are rated on a scale ranging from poor to excellent.

 

Fluorescence

Fluorescence refers to a diamond’s capacity to emit a visible light when its atoms react to long- and short-wave ultraviolet rays. Fluorescence is measured for identification purposes and described on a scale from inert (none) to very strong.

 

Proportions

Diamond proportions refer to the stone’s dimensions and facet angles, as well as the relationship between them. Measurements for round diamonds are indicated by maximum–minimum diameter x depth, in millimeters. Fancy shapes are indicated by length x width x depth.
