CHAPTER VI.
BRITISH GUIANA DIAMONDS.
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.
