Vintage Stunning solid 10K yellow gold statement ring featuring a magical, color-changing square princess-cut central stone surrounded by a genuine diamond halo. Centerstone is gorgeous synthetic Alexandrite with dramatic color- shifting properties. It acts like a completely different ring, depending on your environment. Under cool daylight, it displays a crisp ice-Blue and deep slate teal hue. Step into indoor incandescent, home lighting, and it beautifully shifts into a vibrant mauve-purple and smoky lavender. There is a maker symbol encased in a diamond stamped on the ring inside the band , but I can’t read what it says. Open lattice gallery/basket setting. Excellent pre-owned condition. Comes in a gift box.
