Culet:
The facet at the tip of the pavillion of a gemstone. The culets of older, European-cut diamonds can be seen through the table of the diamond and appear as round, glassy disks. The preferred culet is visible only as a tiny focal point where the facets of the pavilion converge.

Certification:
Before approaching the four "C"s, we'd like to introduce
you to the diamond certificate, or grading report. A grading
report documents all the characteristics of an individual
diamond, including the four "C"s, as seen through a
high-powered microscope by a gemologist. Before
purchasing a diamond, you should review a copy of its
certificate, as this is your only guarantee of the quality and
value of that diamond.
