When faceting, keep in mind how the jeweler is going to set the briolette. Most briolette gemstones will have a hole drilled in them for either a ring or post setting. I prefer to put a 360-degree concave facet in the gemstone girdle for mounting the gemstone.
The briolette lends itself to variety. It can have matching motifs for both the pavilion and crown or have a mixed-cut design as in the provided Acorn design. Since the gemstone is viewed from the side and not the top, one can forgo the concerns of light return and focus on cutting patterns and scintillation of the gemstone. Variations in the length of the pavilion and crown can be explored, but there needs to be proper proportions between the two. The design also lends itself well to opaque, phenomenon and included gemstones.

ROMANCING THE RUBY
Few words are as packed with meaning as “ruby.” While the word refers primarily to the legendary red gemstone, it is also the preferred adjective for red colors of extraordinary intensity and purity. Its association with wealth and royalty conjures romantic images of kingdoms that once flourished in such historical ruby sources as Ceylon, Siam, Burma and India.
