[Rockhounds] Rockhounds Digest, Vol 4, Issue 6

[EDWARD J WAGNER]

This stuff could be jewelers' lacquer. Soak it in lacquer thinner, then rinse w/ acetone. I purchased 4 pink sapphires years ago, and wondered how they acquired their shine. After lac thinner and acetone, they did not look so shiney, or so filled. Ed Wagner--------------------------------------------

 Don't think so.  I put several in varsol
 and nothing happened.  I put a few
 in muriatic acid before leaving for
 Chicago, so will be curious if that
 makes a difference when I get home
 Monday.
