Multi Solitaire Diamond Ring

A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab. Trained gemologists with specialized equipment measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. Brilliant Earth diamonds are certified by the world’s leading gem grading labs including GIA, IGI, and GCAL.

The height of a diamond, from the culet to the table referred as a Depth of the diamond . Depth % is the height of the diamond as a percentage of the girdle diameter.

Table referred as the largest facet of a gemstone, located at the top. Table % is the table width as a percentage of the girdle diameter.

Polish refers to the smoothness of the exterior of a diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and recommended by us for the finest quality jewelry.

Symmetry refers to the angles to which the facets are aligned. Basically exactness of the shape of a diamond, and the symmetrical arrangement and even placement of the facets. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Excellent, Very Good, Good, Fair, or Poor. We recommends diamonds with Good or higher symmetry grades.

Describes the diamond’s response to ultraviolet light. In diamonds with strong or very strong fluorescence, there may be some interference with the flow of light which causes a milky or oily appearance. Canadian diamonds almost always have none to slight fluorescence.

Diamonds with “fancy” shapes are measured according to their length, width and depth. These diamonds will have a longer axis (the biggest measurement) and a shorter one that represents their width. The depth indicates the measurement of the diamond from the bottom to the top. The relative proportions of a diamond ultimately affect its quality and value.

Round-shaped diamonds are never perfectly round even though they may seem to be that way when you look at them. There is a tiny variation between maximum and minimum diameter, so dimensions are reflected as measurements of maximum diameter, minimum diameter and depth.
