Abstract

1,171,212. Polishing gems. SPECTRUM DIAMONDS (PROPRIETARY) Ltd. 18 Jan., 1967 [2 Feb., 1966], No. 2645/67. Heading B3D. The subject-matter of this Specification is substantially identical to that of Specification 1,171,211, but the main claim is directed to a holder for supporting a gem stone during polishing comprising a compartment at its forward end for accepting and retaining a gemcarrying press-pot inserted therein, and an outer movable ring which can be advanced along the holder so that its forward end can be used as a guide to terminate polishing.
