I wanted a positive ID on this before I list it on ebay. It had a label when I received it but it has since disappeared and who knows where to. I believe it was Loma Pinto or something like that. Now is when I wish I had Brad Cross's book....but Mel is very good with sort of thing to. Anyone else wanna chime in...much appreciation in advance. Thanks! steve

Steve: From Cross's book. Loma Pinta Agate "Loma Pintas typically exhibit grayed shades and tints. Pink, light orange and pale yellow and red colors are not uncommon. The banding tends to be comparatively shallow and irregular. The nodules are usually spherical and the outer coating or rind is typically very smooth and reddish brown to light green in color." He has a color plate too Steve and the banding is much finer and tighter than your example, the nodule is very round, more like a Moctazuma, and the colors more muted pastels. if I had to guess ( especially because of the fractures) I'd guess Malawi Agate out of Africa. Colors look right, the banding is coarse, Malawis are almost always fractured a lot, and the crust on your example is within the range of what I've seen on Malawis.....Mel

I bought a box of rhyolite nodules an old timer collected in the "Sierra Pinto Mountains" in Mexico. Looked like Fallon Wonderstone with smaller, tighter patterns. It had more yellow than yours but could explain the name on the label maybe.

Hey very cool you mentioned that John. I've been cleaning up my rough crates and found one of those nodules that has something that looked like Pinto Mtn. on it but the label was too dim to read. Now I can put me a label on and enter it into my type collection. Here's a pic. The rhyolite is definitely nodular and about 2 inches wide. Thanks a lot!....Mel

Glad I could help. The old couple I bought them from actually collected them down there. They used to have all kinds of great rock and sold right by the entry gate at the Joshua Tree show. Last time we sold there they were selling everything and retiring from shows. I got some great deals by the bucket or box. I wish I could get more but I ended up selling the last half box to someone else.
