Bytownite: $.15 to $.55/carat
Bytownite rough cuts into a brilliant, light champagne colored stone.
This rare feldspar comes from Chihuahua, Mexico. Bytownite is an inexpensive and easy-to-cut material cuts a really beautiful stone. Although bytownite usually contains schiller-like silk, it doesn't affect the brilliance of the finished stone.  When placed parallel to the table, the schiller can actually increase the dispersion.

For best performance, raise the pavillion angle 1/2 degree on designs set up in quartz angles.
