Tennis Necklace with lab-grown Rainbow GemstonesA Messy One has no shades of grey; this bold staple reflects that through its multitude of gemstones in all the colors of the rainbow. As science told us a rainbow is actually circular, we decided to put you, the messy one, as the treasure in the middle. If you are more of a double rainbow type, you can combine your necklace with a second one, as all of our clasps are designed to be featured and modular.
