Featured Help with possible Native American silver bracelet

Hi everyone, picked this up this weekend and was hoping for help IDing the mark. I did troll through this site but didn't find it:
http://www.art-amerindien.com/hallmarks/

It's quite small, just fits my small wrist though it was very tight getting it on! Center stone is malachite and there are 2 mother of pears, one on each side. The mark shown below is the only mark on it.

Thanks so much for any help on this

 

It is very nice, love the snake.
I can't find the mark in my books, and it doesn't strike me as NA, with that almost African looking mask. I hope someone finds it.

 

I just sent off an email to the webmaster of the site I mentioned in my original post, I'll let you know if anyone gets back to me.

 

Love it. I presume it is marked sterling or tested? Did you polish it by chance or was it polished by the seller? An interesting combination of the Malachite and MOP. Love the snake symbol and looks to show some wear. You should check maybe Zuni related marks as the snake symbol is rarely found on Navajo pieces.
