sterling silver necklace, from probably the 1960s or early 70s.
made of avocado-green turquoise, and presumably glass paste, set in sterling silver frames, on a silver chain.
marked 925 on hook clasp.

uncleaned, & tarnished. 
when i got it one link was broken (between one of the green glass and baguette shaped links). 
i replaced it with a round, bronze jump ring, and then replaced the link on the other side so it'd be symmetrical.
if you decide to chemically clean this to get it back to a shiny silver color, you'll need to replace the bronze rings with shiny silver ones so they match again.

necklace is 19" around, and weighs 21.11 grams, although i'm sure more than half of that weight is the stones.

IF YOU LIVE IN ANOTHER COUNTRY, MAKE SURE YOU'RE ALLOWED TO IMPORT SILVER BEFORE PURCHASING.
