I ran across a a hundred yards of slabs and boulders of similar material in Mendocino Co. CA. back in the 'late 60s and took samples to a gem stone dealer and other allegedly knowledgeable experts and they all identified it as Serpentine. One of the "experts" who claimed that he was a geologist, said if Serpentine was exposed to extreme heat and pressure long enough, it might possibly become Jade but that Serpentine was too soft to polish to a mirror finish or make jewelry out of. It's definitely a nice looking rock though. PS I lived in Granite Falls for a couple of years and traveled that Loop country deer hunting before the big avalanche happened. Beautiful country.

Bob(AK) 53 Posted March 16, 2020 Share Posted March 16, 2020 Does not look like serpentine to me, but as BMC said, serpentine is soft so check hardness. There are many green rocks 1 Quote Link to post Share on other sites
