Button, button, how old is this button?

[Gormer]

Any ideas more specific than 'old'? I asked a costumer and she suggested 18th/19th C and said I might have more luck on a forum dating it more specifically.

I believe it's glass or rock crystal (bit scratched up on the face of it) and set into either pewter or silver. It's got the little tabby-things on the side (collets?) to hold it in and the back is fully silver/pewter with a little shank.

Thank you kindly!

Hi. Can you show the full back with the shank?

Sure can. It's got a tiny little loop and some dents. I'm wondering if it's spent some time in the ground, perhaps.
