Still greater care and attention are required in this operation than in diamond-cutting: seven months have been occupied in sawing a good-sized stone.
It is not known, with any degree of certainty, whether the ancient inhabitants of the East had any knowledge of the art of diamond-cutting; but it is at the same time very clear, that the nations of the West knew nothing of it till a very late period.
In England, the art of diamond-cutting has ceased to exist, but in Holland it still maintains its ancient pre-eminence; and from thence the cutters of the Koh-i-noor have been brought to perform an operation, which, taking into consideration the size of the stone, had never previously been accomplished in this country.
The diamond-cutting industry is confined chiefly to Amsterdam, where the work employs several thousand persons, mostly Hebrews, the craft having been handed down from father to son through several generations. Much fine cutting is now done in New York also. In this hot and semi-arid country a pan or fontein was a necessity to the Boer farmer, whose chief dependence was on his sheep and cattle.
The operation of diamond-cutting is exceedingly simple, and is without doubt performed by the cutters of the Koh-i-noor at the present time in almost precisely the same manner as invented by Berghen. The stone is held in the proper position by being embedded, all but the salient angle to be cut or polished, in a solder of tin and lead.
