note similarity to the cut rock in this thread... there is only green in this rock,unlike the (awesome) unakite in your first photo. Could epidote be the factor which causes similar qualities in these 2? Rob, I know you have cut some green stuff which also looks like this. interesting! forum.rocktumblinghobby.com/thread/67188/serpentinite-rock-grain

Ok, how universal is unakite? It is not listed in my Audubon Society Guide to rocks and minerals of North America and I have some similar but not quite as bright. I have not taken a hammer to it but mine looks pretty fractured like most of the rocks here. I just made the one cut because I did not see anything in it that I thought I could use. Jim I also have rocks with the same green streaks but the non green part is clear, translucent stone. On the break the clear is kind of like quartz but a break down the green line looks similar to nephrite.

yes, that looks like similar stuff. Unakite is more of a color name for green and red/pink with sometimes white rock, It is fairly common in many places... if it has black it is generally referred to a granite even though it has the other colors... I think there are regional variations on the theme of "what is unakite" but outside of colors in appearances, it seems it can have a variety in composition. (sort of the same thing we run into when defining "jade" )
