Huynh - Hepta Heart
Hepta Heart - Michiko Huynh
This design is for the intermediate. Cut this design in a stone at least 7 mm or larger. This is another good design for the CAM practice. To establish the center point, first cut at 41.65 degrees at the indexes 21-27-69-75. Make all the pavilion facets, except for the facet 16, evenly come to the center point.
The Cone Angle Method (CAM) is a way to cut a girdle outline following a cone with the prescribed angles. The girdle outline could be any shape; round, trillion, square rectangle, pear or even irregular shape. When you cut the cone, the most important thing is you make every cone facet evenly come together to the center point. After you cut the cone, you chain-cut the girdle at 90 degrees meaning linking one girdle facet to the next.
