DIAMONDS FOUND IN OTHER PARTS OF THE WORLD
the farmers is to walk back and forth over the water-washed sands with,

sabots are 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

finders obtain a good price for the stones, as buyers visit the place

small diamonds have been found in meteorites from Australia, Russia,
and Arizona. The meteorite that fell in Russia, September 22, 1886,
contained one per cent of diamantoid carbon in the form of carbonado in
small grayish grains. In the famous Canyon Diablo (Arizona) meteoric
masses containing small black diamonds were found and in one piece
there was discovered a tiny white diamond one fiftieth of an inch in
finding diamonds in meteorites which are fused masses of iron

some form was crystallized into diamonds in the earth by heat and
