then burned and the ashes sieved for the diamonds. The larger ones are
picked up from the ground when seen during the tramp. Many of them are
broken or splintered crystals, and as they are used chiefly for drill
points, most of the unbroken crystals are broken up later for that
purpose. A few are sold for gem purposes. Some of them are white, but a
large majority are yellow or brownish-yellow.
finders obtain a good price for the stones, as buyers visit the place
regularly at certain seasons of the year and usually carry away the
entire output. The quantity obtained is unknown, but the output of
stones suitable for cutting to jewels is inconsiderable.
produces a few diamonds, usually quite small and of inferior quality as
