diamond cutting (diamondkut"ing)

One of three proce es by which diamonds are prepared for use as ornaments or in the arts, the others being diamond-cleaving and diamond polishing. Diamond-cutting is performed by rubbing together two diamonds secured with shellac in wooden holders or handles, one of which is held in each hand of the cutter over the edge of a box called a cutters' box, into which the dust is allowed to fall. This rubbing is continued until each diamond a umes the proper outline, whether brilliant, rose, or briolette, the smaller facets be ing afterward made by polishing. Both stones are cut at the same time, irrespective of size or shape, or of the outline to be produced. Diamond-cutting is sometimes performed by machinery. In this case one of the handles or dops is stationary and the other is moved backward and forward, both diamonds being cut at the same time, but more rapidly and accurately than by hand. diamond-draft (di'a-mond-draft), n. In weav ing, a method of drawing the warp-threads through the heddles. E. H. Knight. diamond-dust (di'a-mond-dust), n. Same as diamond- powder.
