Beginner Barion Oval aka Quake311 - Michiko Huynh
This is an easy-to-cut barion oval. Cut in light colored materials.
It is suitable for the materials with R.I. 1.63 or higher. If you skip the splitters (Pavilion facets 8 and 9), it is good for quartz, beryl and feldspar as well.
About barion
A barion is a group of facets that looks like a crescentic moon and is located under the girdle. Barions may be used in deep pavilions in ovals, cushions, shields etc. They help avoiding overly steep pavilion angles and make cutting easier by allowing a cutter to start with the same angles.
