Excellent detail - measure about 1" just the snake skin part. they are not stamped but tested positive for sterling plus I sold so many back in the day and know where they came from. Apparently they are still being produced - this style - I see them online for $50ish. This is my last pair of these snake earrings. Vintage - got tossed around a bit in storage all these years. They came out of my Luxor Hotel line early 90's. Never worn.
