Ultra Tec has been incredibly helpful throughout my faceting hobby. They've walked me through fixing my old, beat-up, 1970s model machine, repairing the chuck assembly, and a host of other problems. Thank god for the new V5! Works in materials from beryl to rutile (RI = 1.58 - 2.62) with no changes, but I prefer white rutile. Suggested width = 12-25 mm
