Don thank you , the Alberta Opal was solid no glass or class, it was
a flat puke green,and had an almost man made feel about it, it was
being sold by Tee Pee Rock and Gem, from Medicine Hat, there listed #
will redirect you to a home #, I have to call them re. some stone
etc and will enquire again,did you want a small hunk? also the color
inside of the local clam shells is the replacement stone, it’s like
the clam was enclosed in mud and the water seeped into the cavity and
eventually filled it in,it is not the actual clam shell,and
occasionally we do get clams still with color in them just like the
ammonite shell. I have never found any stone around here that had any
play of color or fire in it! altho’ I do find dino gem bones here.
hope to hear from you Tom.
