Need help on torquois and silver necklace.

I also ran across this one today. I had seen one at the flea market for about $200. I didn't get it because I know nothing about this kind of jewelry. The vendor said hers was sterling silver. As you can see, there are stampings on the reverse. I don't know what they mean. I tried the name but I'm coming up empty handed. Any information would be greatly appreciated. Thank you.

And I *think* the stamp over her name is for the Atkinson Trading Co.

No idea what the other stamp is though.

 

Oh wow, that's awesome! Thank you for the link! It was my moms. She left boxes at her old house, someone broke in but I guess they didn't like this and passed it up. She didn't want anything else, so she left the boxes and moved across the country.
