Iolite - $4 to $20/carat
Locality: Madagascar

The hardest thing about cutting Iolite is finding clean material that has the color where it can be faceted. It is very difficult to find decent sized pieces that are thick enough and good enough color on the "c" axis to cut anything. There are few stones that can match Iolite in color, at one time stone dealers hoped that it would be a good (cheaper) Tanzanite, but the rough quality and production have just never happened.

Note: This material has been hand cleaned. If you are familiar with this rough then you know how hard it is to get clean and how rare clean material is. This is all clean.

Iolite has very strong pleochroism, straw color/purple blue depending on the axis and you orientate for the blue/purple. It cuts fairly easy and I recommend that you start with a finer lap (600). Iolite works well in most brilliants and step cuts. Barions in general are not a good idea.
