Does anyone have a clue as to what these might be? Thanks for any help that you might provide. Bob

Hiya Bob, That's a familiar dendritic limestone - cuts a lovely cab - a little soft maybe but lovely patterns and colours. I've got a couple stashed here awaiting further works! Unfortunately I have no further insight as to location etc... Other than USA. Hope this helps a little, Cheers, Harry.

Second one looks like amethyst sage.

Man, those dendritic material can be tough to ID. There is a solid gold type of ammy sage so Rich could be right on that one. The are also gold dendritic jaspers out of Wyoming called sagebrush jasper and also named after several passes in which they are found. The pinkish one if soft, does bear a resemblance to several of the dendritic limestone types. I've got similar stuff I collected at Lake Valley, New Mexico but it comes from a lot of locations. We have gold limestone with dendrites here in Texas too. I've got it all over my rock gardens.......Mel

Thanks everyone for the help. Mel, The pinkish one is quite hard, almost as hard as Agate so it really has me baffled. Bob

If it's hard like a jasper it's got me stumped. There are some dendritic wonderstone type rhyolite materials coming out of Mexico but I've not seen the sort of pattern our example shows. Very pretty stuff anyway....Mel

I got mine from a chap in North Wales - but all he could tell me was that it was American in origin - no definitive location. But looking at your slab it sure does look similar! Two 25x18mm Cabochons I cut last year.
