diamond-cutting (dTft-mond-kufint), n. One 
of three processes by which diamonds are pre- 
pared for use as ornaments or in the arts, the 
others being diamond-cleaving and diamond- 
polishing. Diamond-cutting U 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 con- 
tinued until each diamond assumes the proper outline, 
whether brilliant, rose, or briolette, the smaller facets be- 
ing afterward made by polishing. Roth stones are cut at 
the same time, irrespective of size or shape, or of the out- 
line to be produced. Diamond-cutting is sometimes per- 
formed by machinery. In this case one of the handles or 
dopa 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.

any additional nodes that it may have niugt lie at one or 
more of the dianodal centers. Dianodal curve, a curve
