A complete diamond saw in nicely polished condition and original paint.
These devices were used to cut rough diamonds instead of cleaving manually. This allowed the stone to be used to the maximum.
These devices were set up in series on heavy benches and were driven via a belt (at the front). Between the two discs on the front was a thin copper plate smeared with "Bort" (a mixture of oil and diamond shavings) which saws through the stone, placed between the two markers.
The device ensures that the stone to be cut can be placed in any position above the blade. The sphere, filled with lead, puts pressure on the stone.
Depending on the size of the stone, it could sometimes take two days for a stone to be cut through.
