Small crystals

[605dano]

Found these the other day and thought they looked pretty cool under magnification. I particularly liked the leaf shape in the small vug in the pic with gold coloring. Any thoughts?

The black crystals appear to be either tourmaline or hornsblend. The gold material is in a dendtritic formation, dendrites are a leave or tree like formation, so I'm curious if you have gold there as pyrites dont take that formation that I'm aware of. Seems it'd be a shame to bust it up to find out. Nice micro sample.

Amphibole is another possibility.
