Alberta opal & opalized clams


#1

Can anyone tell me the scoop on Alberta opal and how it’s worked? I
recently viewed some green ick at a rock show and was told that it
was Ab. opal? Also I’ve found some stone of sorts inside of
pertrified clams in the bear paw shale formations, smocky lavender to l.
pink, what is it?

Hi Tom. I have been in the opal business for almost 10 years now and
this is the first I have heard of the Alberta Opal. Did they claim
that this is a new find??. Does it have a play of color??

The lavender to pink in the clams are almost certain to be mother of
pearl like the Anomies from British Columbia. The Fox Formation in
South Dakota also has shells with the mother of pearl still visible.

Can anyone tell me where would be the best pale to souce for natural
Opal with three colours. I would appreciate very much Thanh Ha

I am guessing that what you say was ammolite, which looks (to me)
like dragon skin :slight_smile: It comes in shades of red, green, and
purple-blue. It is only found in Alberta, Canada.

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.
