#1 Will a knife scratch it? Streak test? Magnetic?
#2 Diorite is one candidate.

#2 Diorite is one candidate.

Thank you for your opinion

All three are:
not magnetic
harder, than stainless steel paper knife
#1 I am thinking about jade
#2 smaller one has white metallic inclusions and overall they look close to turquoise with some kind of black quartz inclusions

Do the streak test; rubb against a unglazed piece of porcelain. What colour do you get?
I'm more inclined towards a metallic-oxide or sulphide.
