Tris de Garnet
by Tom Herbst
This is my first gem design. Tris de Garnet is a very simple design -
9 pavilion and 10 crown facets. Nevertheless, it produces a lot of "action,"
due to its asymmetry and odd number of mains.
Note the cutting order. I originally designed it with an initial cut
to center-point with the steep (54 degree) facets - the usual "outside-in"
order. This can be very wasteful of rough, and I learned a great deal
figuring out how to do the CAM and then "inside-out" order.
The name derives from the original GemCad filename: TRIS for Triangle,
Simple. I named it after one of my favorite dishes, Tris de Pasta, which
is a mix of three types of noodles and sauce. This gem also mixes things
up pretty well (light, anyway), so the name seemed a natural.
Tris de Garnet is a very simple design, and it is appropriate for faceters
with all levels of experience. It appeared on the OPLC
