Dichroic glass is created by joining multiple, ultra-thin layers of various metals, and it’s those layers that cause its colors to glimmer in the light. To make this necklace, dichroic glass is placed into sterling silver to shimmer in shades of blue, pink, and green. Pendant is 1.25" and hangs 1.7" with bale. Sterling chain adjusts 16"–18" and has spring ring clasp. Artisan-made in USA; colors may vary slightly.
