Fresh Estate Find.
I know very little about jewelry. I will tell you what I know and take lots of photos for you.
Purchased together in a small box with no other items. They appear to be a set. Use your judgement.
Round neck collar, choker style with a large concho style Star Pendant & 2 matching earrings.
The collar is stamped "Mexico 925 CII". The collar is approx 14" long. The large star is 2" across. The earrings are 1 1/4" across.
Beautiful patina and in very nice condition.
See Photos, they are part of the description.
