Τ
is known that Diamonds occur in British Guiana, but little has hitherto
been, done in systematically searching for them. From time to time,
those who are engaged in washing gold, in the placer diggings, find
crystals of Diamond ; and some of these have been described as
well-formed octahedral crystals, of excellent colour and quality. The
gravels of the Mazaruni River are noted specially as being
dia-mantiferous. In 1891, some prospecting parties from Georgetown
proceeded up this river, and obtained a number of small Diamonds, but
this success does not seem to have been followed up. The present state
of our knowledge does not justify us in predicting anything as to the
probable future of British Guiana as a Diamond-producing colony.
