Addition # 10 – Cut this in refractive indexes 1.54 to 1.76 with no changes. Got a deep small triangular shaped piece of rough? That is what this design is for. Use this in lightly saturated materials, it is ideal for Afghan Tourmaline nodules. Which is what I designed this for, a lot of that rough tends to be slightly triangular in shape and pale in color. Note: C2 only meets in corners and C3 only meets C3 in the middle. Cut them as evenly as you can. This is not difficult to cut but keep in mind that you may need to tweak a little on C2 and C3. On a small stone a table can be cut at C4. On a large stone a table can be cut at C5.
