Hello, we had a real mess in our basement this week, a sewage back
up. In cleaning up I find that my rough stock of Spencer opal has
been slightly dampened. The cardboard box and the rock it contained
were wet on the bottom. Now, this rock has not been trimmed yet, and
some of the pieces are about the size of cantaloupes (with small
pieces of opal). I need a good process to sterilize the rocks and
leave the opals intact. Somewhere in the back of my mind a little
voice says that a 1/10 solution of bleach may cloud opals. ?? What
about hydrogen peroxide or alcohol?
All answers greatly appreciated.
Sincerely yours, Rose Alene McArthur
