The Long Rainbow Quartz Necklace comes in two colors: purple and blue. It has a long chain to resemble elegance and a minimal yet fancy wire design. The chain is 27 inches long and closed off by a lobster claw. The stones used in this necklace are Rainbow Quartz stones. I used 22 gage wire to wrap the stones. NATURAL SIZING ACCUSERS. All of the Quartz are close in size but there are slight differences in shape and size. The rock necklaces are HAND MADE with care and durability. I strive for durable, fashionable accessories and a passionate future. If you have any questions or concerns please do not hesitate to contact me.
