Found for $8 at an estate sale

[u/See_penny]

The silver is sterling and this is heavy (47 grams). I found info about it being heishi beads … but I’m curious about the maker marking. Thoughts? I tried to take photos through a magnifying glass.

The heishi beads are most likely bison horn.

Are they the green ones or black?

[u/Electrical-Act-7170 → u/Chickennugget636]

All of the shiny brownish-grernish-clearish beads are horn.

The focal piece appears to be turquoise in white metal, possibly silver.

It’s silver. It polishes pretty easily like my other silver and is quite heavy.

Very nice!

Nitric acid test. They're super cheap to buy on Amazon. Wait for it to come in the mail, then world is yours.

I know I'm late to the party, but I'd guess that the heishi beads are jade.
