ALEXIS KIRK Two Tone Metal Modernist Hinged Collar Necklace is by one of my very favorite designers. I have just acquired a large portion of the estate, and will be listing pieces over the next several months. The piece is a classic design of 1970s simplicity. The hinged sides make for an easy fit. It has a hook back closure and measures approximately 16 inches closed. These pieces were sold in high end department store such as Saks, Neiman Marcus and Bergdorf Goodman's. He sold to many stars and royalty, and did a lot of work for show's such as Dynasty. He was one of the most diverse designer's of his era, doing everything from necklaces to belts.
