Backstory: a character is a prisoner and has a pearl (about 1 CM diameter) that he wants to keep on his person at all times but he doesn't want his guards to find it. A friend of the prisoner with medicine skills has offered to sew the pearl into his flesh so that he'd never lose it and at the same time it's unlikely to be found. My big question now is where?
I know that in history there are cases of people sewing jewels into their arms but I haven't had much luck in googling exact information about that. My boyfriend thinks that the side under the ribs would be the best place. I thought it would be a good idea to check with this community.
I've searched "sewing jewel into flesh/skin" "how to sew jewel into flesh/skin" "stitching jewel into flesh/skin" and variations on that.
EDIT TO ADD: Thank you, everyone, for your suggestions. I didn't consider that the pearl would have to be encased first, but I'll make sure to include that detail now in my story.
