Park Lane Massive Cushion Cute w/ Scalloped Halo Cocktail Ring

Park Lane “Go Gaga” massive cushion cut cocktail ring with scalloped halo. Elegant gold-tone with a massive faceted clear stone on an elevated setting. The chaton halo stones may have an AB coating. This is advertised as a CZ and definitely has the shine. It tests high glass on the Presidium Gem Tester II. A striking statement piece that is perfect for a party look. Face is 0.75” x 0.75”. ~5/8” height. Not signed Park Lane. This has been well-loved, but the top visible portion still looks good. The bottom of the band and part of the sides has faded to silver-tone. The interior of the band has some verdigris. Hardware does not take a magnet.
