Depth %: Height divided by width. Determines brilliance and sparkle.
Durability: The ability (in gems or metals) to withstand wear, heat, and chemicals.
Depth %:
The height of a diamond (measured from the culet to the table) divided by the width of the diamond. The depth % is critical to creating brilliance and fire in a diamond.
DIAMOND DEPTH %
Depth refers to the distance between the culet and the table when the diamond is viewed from the side.
Depth %: Height divided by width.
Eye-clean: When viewing with the naked eye, a diamond with no visible inclusions or imperfections.
Facet: A diamond's flat, polished surfaces.
Depth %
This number indicates how "deep" a diamond has been cut. For round diamonds the depth should not usually exceed 64% unless cost is a major factor. Diamonds with smaller depth numbers tend to have a larger diameter (see measurements above).
They provide only the table % and total depth % for the stone. Therefore, it is not possible to determine the individual contributions of the crown, girdle and pavilion to the total depth and no crown or pavilion angles are given.
Depth Percentage (%): There are two different measurements of a diamond's depth - the actual depth in millimeters and the depth percentage, which expresses how deep the diamond is in comparison to how wide it is. The depth % is critical to ...
The example table indicates a Standard Brilliant cut diamond would (hypothetically) lose 22% of it's weight if it were recut to the proper depth %, and an additional 6% of it's weight for a proper table %, ...
of a diamond, and from these measurements you can determine the quality and grade of a diamond's cut. Getting the right depth and table percentage is critical to maximizing a diamond's brilliance.
Table % = Table/Diameter
Depth % = ...
