Convertible necklace from Sarah Coventry features three interchangeable resin pendants which hook onto the chain with a mechanism that resembles a clip style earring back. That's where the signature can be found as well. Each of the pendants measures 2 1/2 inches long; the chain measures 26 inches long. The set dates to 1974 and was called "Triple Treat". The colors are beautiful and include turquoise, deep coral, and ivory colored pendants. The set is in fine shape with no issues at all.
Resin convertible style necklaces were quite popular at this time and were made by many companies, including Lanvin, Christian Dior, and Trifari, to name a few.
