Vintage Kafin Semiprecious Stone Slide Bracelet with dangle charm

Vintage Chunky Kafin New York Gemstone slider Bracelet Gold Tone with safety chain and box insert clasp. There are 6 multi gem stone sliders and a dangling charm on this exquisite piece! 7 inches in length. Item is pre-owned and has normal wear for the age of the piece. The piece is from the 1950's-1960's. It has one missing stone (shown in pics) and the clasp on the safety chain broke and previous owner did a repair (shown in pics too). Not 100% sure of value, I have seen prices ranging from $40 to $140. I believe a fair price for the condition is $75, but feel free to make an offer!!
