THE CUTTING OF PRECIOUS STONES 69
decided
to make 66, and, as already pointed out, these stones are, up to the
present time, the most magnificent in fire, beauty and purity ever
discovered.
The
positions and angles of the facets, as well as the number, are of
supreme importance, and diamond cutters —even though they have rules
regulating these matters, according to the weight and size of the
stone—must exercise the greatest care and exactitude, for their
decision once made is practically unalterable.
