Need help with this one

[tavmar]

what is this? First time ever seeing something like this. I’m new to this hobby I’ve come to during my “identity loss” that comes with my medical issue late lymes disease. I would appreciate any help I can. Bare with me I’m sure I will be asking about a lot of finds I’ve found. Thank you all that comments.

something like granite with mica flakes.... in anycase, it is an intrusive igneous stone with slow crystal growth over time.
