Featuring an ever-changing range of oil-slick colors, this quartz crystal triplet is a great choice for designs that call for a unique, unexpected stone. Use it as is to create a simple pendant or pair it with an assortment of other complementary-color stones to create more complex necklace designs and matched sets, including bracelets and rings. This triplet is composed of a faceted clear quartz top and bottom; the adhesive that holds the two together provides the beautiful black rainbow effect.
