I recently found this artifact metal detecting. It appears to be a charm with a tiny drop of blood in it but I am not sure. I'm not sure how old it is and what it would be used for. Any insight it greatly appreciated. It is around half an inch in length and width.
Well that's something I never knew existed as a Christian necklace emblem... although I'm not seeing a seed in the pictures that looks like the examples shown on the web.
