3.78 ct. Topaz with 'Pinwheel' Inclusion

Color:  Colorless Clarity:  Slightly Included
Origin:  Burma Cut:  Round Brilliant
Treatments:  None Measurements:  9 mm

It is occasionally possible to find these interesting stones that are completely clean save for a single needle (or small group of needles in this case) that are cut to reflect this inclusion in a 'pinwheel' around the stone.  The way to accomplish this is the orient the stone so that the needle goes directly from the culet up through the table of the stone.  Quite interesting - and particularly of note here is the host material - Topaz is quite uncommon, the vast majority of these are Quartz.
