intensify any tint of yellow existing in the stone. This observation
does not apply to river stones, but rather to those from the dry
diggings. In many specimens a spot is developed after cutting, which
was not visible in the rough. This spot may appear even in the finest
Diamonds, and is especially noticeable in Indian stones.
It
is impossible to quote a standard price for Rough Diamonds since the
price is subject to much fluctuation. The remark universally applicable
is that the value varies greatly, according to the size, the shape, the
colour of the stone, and its freedom from flaws.
