Re: Rock with numerous crystals, unknown origin
It looks rather like quartz stained by sulfur. The pieces I have are from somewhere between Syracuse and Schenectady, picked up by my father many many years ago.
Does your father still pick up rocks in DE or VA? If he's willing to share the information I'd love to hear about any good collecting locations in the MD/VA/DE area.
