    $\begingroup$ Looks like rounded olivine... But olivine is 6.5-7 on Mohs scale $\endgroup$ – JulPal Jun 8 at 10:19

    $\begingroup$ I would say it is a metamorphic rock on greenschists facie, with chlorite and/or epidote giving the green color. I am not sure but I think I can see foliation or lineation. That would be not rare at Highlands but a tick to precise location could allow to search if it was found on a metamorphic layer. $\endgroup$ – user12525 Jun 8 at 15:22
