🔎 UNIDENTIFIED Wyoming jade?

[sjbrdn]

Hey Guys. I'm a newbie. I've always been interested in rocks and have a small collection but I've never really delved into what they specifically are, etc. My family lived in Wyoming in the 1970's when I was a child. My father acquired this stone at that time but I'm not sure how. He worked for Pacific Power on a road crew and did a lot of hunting, fishing and camping with the family, so he could have acquired it in a number of ways. It's been cut on one side. Could this be from the mining process? It weighs just over 14 pounds.

My father told me it was Wyoming jade. I understand there are many types of jade. Some being desirable while others are not. The pictures show the rough sides and the cut side. I wet the cut side in one picture to better show the makeup of the stone and give an
idea how it would look polished.

I appreciate any help you can give me with identifying this stone.

Steve

Wyoming jade is Nephrite jade, it is the State's gemstone and is considered as some of the finest in the world.

There are two types of jade Nephrite and Jadeite, with Nephrite being considered to be the best.

Wyoming jade comes on many colors from black, white even blue but mostly it comes in many shades of green.

Jade is translucent or at very least opaque, I can't tell from your photos if yours is or not, can you post another photo with a bright light behind to see if it's translucent?

Thanks for your reply. I read the article and others on the subject. It seems there are different grades of jade based on purity (and impurity) with the finest exhibiting the translucent qualities. The article references other jade-like stones that are magnetic.

This stone is 14# and in the rough with the exception of the cut side. I don't think it is translucent and it's not magnetic either. Looking at pictures from other Wyoming jade sites, it resembles samples in the sage color scheme with imperfections.

Of course, this is all a wild guess on my part, that's why I'm looking for some clarification from more knowledgeable people.
