Jewelry Vocabulary Guide

Here’s a brief jewelry vocabulary guide, I would like to eventually expand with the help of our awesome readers!

Bezel – The metal around a stone that keeps it in place, e.g. sterling silver bezel.
Bezel set – Stone kept in place by the use of prongs.
Cut – The type of shape the gem is ‘cut’ into. The cut is either faceted or non-faceted, e.g. cabochon cut. Here’s a brief guide to cuts, more to come later. Cut is graded into excellent, very good, good, fair, and poor cuts.

  • Brilliant Cut– It’s a facet cut that ensures that when light reflects, it gives a unique burst of brightness, almost like radiating fire.
  • Cabochon– A stone that is flat at the bottom, but round on top; smooth without facets like a pebble
  • Fancy Cut– Several possible shapes, such as kite-shaped, lozenge shaped, triangular.
  • Mixed Cut– Usually rounded in outline, cut as brilliants with pavilions step-cut. Rubies and sapphires are the easiest to shape into a mixed cut.
  • Step Cut – Step cuts come in a variation of shapes; oval, square, octagons, baguettes, and general table cuts. The step cut is also known at the ‘emerald cut’. This cut intensifies the hue of a color.
