GRS I.D. Ring Holder | Precision Ring Engraving & Stone Setting Fixture for Jewelers
The GRS I.D. Ring Holder (004-735) is a professional jewelry workholding fixture designed to securely hold rings and cylindrical pieces from the inside, providing exceptional stability for engraving, stone setting, polishing, and detailed jewelry repair. Designed for use with GRS blocks and vises, this compact and versatile ring holder delivers the secure grip needed for precision bench work without the bulk of larger ring fixtures.
The unique expanding mandrel system applies even pressure around the inside diameter of the ring, minimizing distortion while maintaining a secure hold. The included standard cones allow controlled ring rotation for engraving and stone setting, while the locking cones provide a firm, non-rotating platform for operations such as bead raising and pavé setting.
Ideal for professional jewelers, engravers, and repair technicians, the GRS I.D. Ring Holder offers the precision, flexibility, and durability expected from GRS workholding tools.

Why Choose the GRS I.D. Ring Holder?
Holding a ring securely is essential for achieving clean engraving lines, accurate stone placement, and professional finishing results. The GRS I.D. Ring Holder supports the ring internally, leaving the outside surface accessible while reducing movement and vibration.
Unlike simple ring clamps, the expanding mandrel design distributes pressure evenly inside the ring. This gives jewelers greater control when rotating, positioning, or locking the ring during complex operations.
