ex-Bill Rudner.
Way back when, a person could stop by Chris Wright’s place in Hot Springs and go through a bin with boulder opal rough. It was sold by the pound. That was okay because about 99.99% of it was ironstone matrix. I suspect that possibly as many as a dozen people have high-graded it before it got to the bin but every now and again Chris would put back a piece for that special person. Unfortunately, more often than not, I was usually not that person. (Author: Don Lum)
