This is a total rebuild of the old version of this design. For some reason, the domed crown reminds me very much of an igloo. Yes, the variable checkerboard crown gets tedious and errors compound, but if you prepolish from the top down it should be fine. Works in materials from beryl to rutile (RI = 1.58 - 2.62) with no changes, and should serve as an excellent choice for flawless, pale materials of any type.
