Rough
Opal is opal in the form
in which it comes directly from the mine. There are various types
including black opal, white opal rough, and boulder opal rough.
When the tough laborious extraction of the opal from the mining
site is completed, another stage begins-- the refinement of the
stone into the beautiful opal gem.
The process of rough shaping, fine shaping, sanding,
and final leather polishing, in combination with a patient mind,
can transform the rough hewn rock into an object of true beauty...
nature's own dazzling fireworks!
Many enthusiastic professionals and hobbyists
have turned a handsome profit by purchasing low-cost rough stones
from Opal Exchange and turning them into quality gems.
