about the size of a fat football, mohs 5 approximately, my good quality pocket knife leaves a barely noticeable surface scratch when applied vigorously, white areas quite translucent , green not quite opaque. Light might shine through a thin section a bit, you can see the vesicles of white just below the surface in the rock. Some of the smallest inclusions look square, so am thinking the white may be calcite. ? scratch plates don't leave marks with either white or green areas, doesn't smell of sulfur when scratched, I can only smell the scratch plate, earthy smell. very dense, hoping somebody with more experience will recognize it, I can't find photos of anything like it, but sometimes you need to know what to search for. With the vast combined experience of this group, I am sure somebody can tell me what this is. help? thank you

Cool rock, snowman. I'd guess it's a Peridotite. Looks like it has some interesting sulfide mineralization going on too. Check those orange stained areas out for metallic inclusions!

Great, thanks for the ID guys! Shotgunner would love to see what it looks like when cut...there are hints of deep bright green beneath the iron staining... did you make a sphere of it?

Just landed yesterday! Lol Haven't cut a rock in 8 months. Hoping that will change with a new addition to my household next month.
