I have a stone and am curious on what it is

The rock was found around 30 years ago in the mid 80's around Alma Colorado. It is 11 3/4*11 1/2*8. Roughly 30-50 lbs. Maybe you can tell me what it is? https://photos.app.goo.gl/OKryfCezKIXJ1Vhw2

There appears to be some opalescent quality to it. It could have opal in it.

The top photo also has an appearance similar to iris agate. Though the pictures really are not clear for good identification.
