The place it was collected is unknown. I bought it from a rockhound friend who doesn't share his hunting locations.

Welcome to the Forum from Texas :wave:

Your rock looks like Unakite imo. v

"This metamorphic rock is formed when granite is altered by hydrothermal activity. Unakite--also referred to as epidote/epidotized granite--blends green epidote, pink orthoclase feldspar and clear quartz and can contain trace amounts of other materials such as magnetite or zircon."

With the green on it I would think some copper is in it along with some Iron or galena and rose quartz it came from a highly mineralized area probably from a tailings pile at a gold mine it also looks like maybe some sulphur in it also. IMO I have found some beautiful turquoise at a gold mine in the tailings piles as it wasn't what they were after but your specimen would say they were on the trail of gold because the minerals run together.
