Description

GREETINGS TO ALL!
RECENTLY AQUIRED FROM AN ESTATE SALE
I am not sure if this pre-dates 1935-any information on this would be greatly appreciated!
Vintage Sterling Silver Native American Navajo Turquoise  Necklace.
Pendant part is accented with four attractive blue turquoise stones.
Back of the pendant was slightly polished-to get a better view of the signature and that reads CPH, (with a squiggly) line, STERLING .
Feel free to inquire before placing a bid .
THANKS FOR LOOKING!
