Thanks for all the replies. Out of Time- to answer ur question the top pic was the first one I found, which my boys have temporarily misplaced, but it was about 1” wide and 2” long. The newest find is about 2” wide and 2” long at the broken part. It’s much broader and heavier. Arrow86- quartz/crystal is not a common stone down here, at least in sw Florida anyways. I would definitely go with Toddspoint, being more of a coral material, especially given I'm surrounded by saltwater? I will do more research. When I found the first one it was cool, but finding another one has sparked my interest, lol. Is it possible for arrow heads to end up down from other places in the country?
