We carried these liquid silver necklaces in our store in Colorado clear back to the 1970's and we literally sold them by the hundreds. The young ladies who came on the teen tour buses from New York or Boston always had to have at least one and most of the time a couple... one with turquoise and one with coral, that was about the only choices we had back in the 70's.
These necklaces are made of Sterling liquid silver with turquoise and wild horse magnesite rondelle beads.
