Snitzer Sam2 Bottom Tang For Extra Large Stones
 
Is the same dop as D1700B, except that it is delivered with a bottom dop for extra large stones (D1980). It has a capacity up to 500cts. This dop is capable of polishing diamonds at any angle while maintaining the exact level, the polishing is done at the center point of rotation of the dop at all times. It comes also with a highly accurate, adjustable water level. The anti-backlash L/R facet screw and of course the sturdy design of this tool allows the polisher to get the highest possible geometric precision and better surface quality, never attained before on the largest of stones. Comes with grub spanners and tail.
