Quality - Tradition - Innovation Everything for Jewellers & Watchmakers

This ring holder, designed by world-renowned stone setter Alexander Sidorov, is the result of many years’ experience in applying and teaching stone-setting techniques. The “Alexander” ring fixture mounts directly onto the GRS MicroBlock, opening up limitless possibilities for engraving rings and setting gem stones.

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 different sizes of horizontal drawbars so it can accommodate rings of virtually any width. The vertical ring holder features a spherical base that permits multi-axis movement for optimal access to your desired work surface. The fixture also includes two full 10-piece expanding mandrel sets placed in a high-quality aluminium tray. (The GRS MicroBlock is sold separately.) 

The “Alexander” ring fixture includes: 2 bell-shaped jaw attachments, 6 button-head cap screws, 1 wrench, 1 short horizontal drawbar, 1 long horizontal drawbar, 1 vertical drawbar, 2 plastic standard cones, 2 plastic locking cones, 1 steel standard cone, 1 double-sided cone, 1 cone cover, 1 countersunk screw, 20 expanding mandrels and 1 aluminium storage tray.
