I got these specifically from NachoWyomingJade and her black jades are definitely really good quality! Her Edwards Black is expensive as expected but she has some that
may have came from Edwards area but were then scattered around to various other rivers and creeks in Wyoming. I'd say definitely visit her if you're looking for palmstones or specimens pieces to display.
Another shop I wanted to shoutout is Really Old Rocks ran by Bob Scholl, similar to Nacho but he also has some carvings for sale, and lists down where he got his jades from sometime down to the geographic location.
So yeah, these 2 shops are where I'm currently obtaining some black jades and hopefully a few Edwards cobble for my own.

Also I can relate to that since Edwards can easily destroy my bank account if I ever thought of buying a good chunk of it from someone, or a finished product that's large in size.
Oh one more thing, Bob and Nacho both have told me that there are black jades that can rival the same quality as Edwards in terms of tight grain, uniform black, and high gloss without needs of polishing. So do keep that in mind that there's still black jades in Wyoming that can achieve Edwards black jade quality in both color, and luster.
