Please id .I have no clue of anything about this bracelet. It does not have a mark

This is called a Navajo sandcast bracelet. It appears to be a piece of turquoise. The technique to make this is one of the first Navajo silversmiths learned. The design is carved into a stone and silver is poured into the carved pattern. It would be difficult to give you an age, cuffs just like this are made today.

Thank you so much .I know it was my grandmother’s ,she never told me the age or anything. Just curious if it would be valuable, it is to me with it being hers .but wondering what it’s worth.

It looks like a heavy piece, sandcast is a popular style. I would say this would be $250 - $300.
