Victoria, I have a small book (76 pages) that explains opal cutting
from beginning to finished product. Name of the book is: Opal
Cutting Made Easy by Paul B. Downing Published by MAJESTIC GEMS 7
CARVINGS, 3412 Monitor Lane, Tallahassee, Florida 32312. It was
copyrighted in 1984.
Whether you would still be able to get the book from the publisher
or not, I don't know. You might possibly be able to get it from an
opal dealer, The House of Tibara, 7573 North Fancher, Clovis, CA
93612. I don't have his phone number.
I hope this helps you....best wishes, Kelly
