Beginner Rectangle Cushion - Michiko Huynh
This is an easy-to-cut rectangle cushion. Cut the barion following the diagram. The meets on the crown are easy to adjust while pre-polishing. Cut in light colored materials. This design seems to deepen the color.
It is suitable for most gem materials.
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.
