I’m still learning! Based on my field guide this could be Chrysocolla, Spiderweb Turquoise, Variscite.... all have samples that look similar. Appreciate help with actual ID and especially appreciate help with what specific elements you’d use to ID. Thanks!!!

Did you cut them yourself? Or do you have any raw material. Hardness test would be good and as for the coloration I'm not certian with your thoughts because the minerals you mention have more pronounced coloration as well as habit.

It could be some sort of porphyry, but I'm not sure. This is andesite porphyry. Gary
