As you may have noticed, buying a diamond comes complete with a heaping pile of intricate facts and details that only make sense to industry insiders. Facts like, “a modern round brilliant diamond has 57 facets plus the culet. The faceting pattern for a round brilliant is fairly standardized, so the degree which each facet conforms to the ideal determines the cut grade.” Or “fancy cut diamonds, like cushion or heart cuts, have a wide variety of pavilion faceting patterns, each of which produces a different effect of brilliance and scintillation.”
Frankly, it is hard to keep up with all the insider talk. Luckily, we are here to help with these handy diagrams! Use the graphics below to help remember what those fancy gemologists mean when they are talking about the different aspects of your diamond.
In this post, we are going to cover:
The Crown’s Facets
The Pavilion Facets
The crown is the portion of the diamond above the girdle.
The pavilion is comprised of the lower bezel facets and the pavilion main facets. In plain terms, the pavilion is the lower half of the diamond.
These are the measurements and angles that determine a round brilliant’s “cut” grade, and are found on most diamond certificates.
It is’nt possible to accurately measure these proportions by hand, they are automatically determined by specialized systems that use a high resolution digital camera for the 3D modeling of the diamond.
