The radiant cut is a modified form of the rectangular barion cut.

The barion cut ( actually only pavilion )was designed by Basil Watermeyer, a diamond cutter in Johannesburg, South Africa. He has used it with the ordinary step crown, and found it to be excellent with diamonds. This is another instance of where amateur faceter owes much to the diamond cutter

The barion cut use a revolutionary principle. All pavilion facets(except the long break facet on each side) are no more than four degrees greater than the culet angle. Also, a good number of facets end as a point at the girdle. The stones remain true square and rectangle by having the facets end at the long break facet. Mr.Watermeyer calls these halfmoon facets.

The result of this new concept is startling. The stones, even though they have ordinary step crowns, are extremely brilliant throughout. Each side and end of a gem shows a spray of brilliance begining at the culet, and spreading out at the sides. Mr.Watermeyer rightfully calls this "fountaining". To say the least, it is spectacular.

Our radiant cut has the scissors-cut style crown and modified barion-cut pavilion. This innovating cutting yields a greater brilliance because its' facets allow more light refracting surfaces. It is the ultimate in brilliance in the rectangle and square stones.
