So awesome to figure out what those are! Super hard stone.. the first didn't look like anything, but once it got cut back some, the color was nice, so.. kept going.. the backside has a lot of metallic inclusions, in between the green.. it was very hard to polish and took ages, but the metals show with a nice flash.. I've already passed it on and don't think there is a detailed photo.. but there's a 10-pound chunk on the table of the blue gabbro.. might see it there..
Appreciated your thoughts on "Jadezilla".. it does have sections of bright blue green and deep blue.. but it's not translucent that I can tell, except in places where quartz has filled the fractures.. of which there are almost none. Not a single chip.. it's incredibly hard! No foliation of any kind.. Turns out someone else found this very stone 2 years ago, posted pictures of it on Reddit. They attacked it with a hammer, but couldn't chip it and gave up.. Obviously they never returned for it, but funny I would find a picture of the rock online.
The one that looks like a big gecko head or a pair of lips depending on which side you're looking, that's the same kind of stone, about 35lbs. It's got sections of what appear to be metallic gold or copper, you can kind of see the speckles above the "lips". This cobble suffered quite a bit, so I had to cut it back pretty far to get past that on one side. There's another one just like this that was more flat, so it's being made into a bowl, but it has the same color, banding.. inside is the same.. kind of grayish in places, blue, green with that bright yellow running all through, so if you step back it looks green, but it's not exactly.. it came from the same place. They called it jade, and I hesitate.. people get pretty loose with that word; but whatever it is, it's lovely.. I love the metals that reveal themselves.. Seems the outer layer took a very nice polish, but the inside was more challenging..
The book my twin has also, I should get a copy of my own! There's actually a gem and mineral club just up the street here, but the stuff I'm working on is always so big.. and I'm quite shy lol
