DIAMOND MINER.

Diamond-cutters at work there, each furnished with a single wheel of steel, the size of a dinner-plate. They operated upon but one stone at a time, but worked rapidly, having Diamond-dust
a discretion.
If the rough stone were clear, they did nothing more than polish its natural faces, in order not to lessen the weight; but if it contained flaws or black and red specks, they covered the gem
all over
with facets to disguise them. So invariably was this the rule, that Tavernier as soon as he saw a facetted Indian Diamond was certain of its defectiveness.

Dionysius Periegetes enumerates the Diamond amongst the numerous gems (the Beryl, Green Jasper, Topazius, Amethyst) picked up in the river-beds by the natives of India, as anciently understood, lying to the east of Mount Parapamissus, and Ariana. Ammian (xxii. 8,30), writing-in the 4th century, mentions the region of the Agathyrsi beyond the Sea of Azov as abounding in Diamonds : " apud quos ada-mantis est copia lapidis."
