This is a lovely vintage Carnelian (agate) beads necklace.
It is rare due to its size, most you see is about 8 to 10 mm only, this necklace is graduated from 10 mm to 15 mm.
It weighs 140.1 grams.
Wearing length is about 25 inches long. All hand-knotted in between beads.
Clasp is the insert filigree style made of Chinese silver.
Condition is excellent, rarely worn and I think it is in mint condition although I believe it is from the 1970's!
A dime is place for size reference and not included.
