Books and Seminars

Tucson has the largest collection of gem shows in the world in one place at one time around late January – early February of each year. We have had a booth at the Holidome for years and in 1999 initiated a series of Opal Seminars. We are happy to report that our Opal Seminar at the Gem & Lapidary Wholesalers Show at the Holiday Inn Holidome in February 2006 far exceeded our expectations. We are gratified with the reception of our seminars on opal mining, cutting, buying, and using our favorite gemstone. The more we all know, the better for the OPAL industry and us the consumers.

for upcoming seminars please check our Calendar.
