I have several pieces of Native American Jewelry with a B and a Y connected at the lower right of the B

Also some pieces with a capital A and a W beneath the A and connected to it, there is also an arrowing running vertically through the A and W. The point of the arrow is beneath the W.

Any help in identifying the artist will be appreciated.

Here are some sites that MIGHT be helpful
