I was out hiking this morning and about 6 miles in on a service road I ran across a green rock that really stood out (first image below). I'm used to seeing grayish/green rocks in New England, and I do find the odd green rock every now and then, but, it is always a lone specimen and always a dull green. I looked around and found several more of these stones embedded in the trail within a 15ft. radius: there were no others on any part of the 8 mile trail. Since they are mohs 6 (and a rarity in my area) I loaded most of them on my back for the rest of the tick-ridden trek. What do you think these are? My first guess would be a type of a MetaBasalt, but, I'm not good at IDs. Dry: Wet:

Interesting if they turn out to be metabasalt because they sure look like rocks that I've collected on a favorite beach in Sonora, Mexico as beach cobble. I've tried to ID them but never to my satisfaction. I'm in Mexico now and will collect a few more than I would have to send your way for comparison. I may have a photos to share if I can come up with the password where the photos are stored. They are hard, I've had trouble polishing them but have not given up yet.

Looks like serpentine to me. Can be hardness of 6. We have some hard serpentine in VT.

In review of various forms of Serpentine online: I think you are right! If it tumbles/polishes decent I might hike back with some tools and do a little 'discreet' recreational excavation in the area.

I've tried to call my specimens serpentine but not to my satisfaction. Yes they are hard. They just don't act like any of the serpentines I've handled from other sites.
