Product Details

GRS 003-783 Alexandre Sidorov Stone Setter's Package with MicroBlock 

Designed by world-renowned diamond setter Alexandre Sidorov, this workholding solution is the result of many years of mastering and teaching stonesetting techniques. The Alexandre Ring Fixture mounts directly to the GRS MicroBlock*  giving the user limitless options for engraving and stonesetting rings.

The fixture features a pair of bell-shaped jaw attachments designed to enhance the function of the vertical and horizontal drawbars. The set comes with two sizes of horizontal drawbars to accommodate rings of almost any width. The vertical ring holder features a spherical base that permits multi-axis movement for superior access to your desired work surface. The fixture also includes two full 10-piece expanding mandrel sets placed in a high quality aluminum tray. The Stone Setter’s Package comes complete with the Alexandre Fixture Set and a GRS MicroBlock.
