This blue iris quartz crystal stone necklace is minimalist but beautiful. I made it with a silver toned chain which is a gorgeous contrast to the colors in the quartz. The quartz gives off cobalt blues, grays, and various shades of purples at different angles. All findings are nickel free. Stone: Quartz Necklace length: 19.5 Inches **I can customize necklace to be your desired length and preferred metal color (silver, gold, brass, black)
