For our Rainbow Stones designs, we use genuine titanium quartz beads that are heat-treated to create their stunning variety of colors. The base of the jewelry is made from gold-plated 925 silver and gold-filled materials. Our Rainbow Stones collection includes necklaces, hoop earrings, and a bracelet, each adorned with one or more titanium quartz beads. The Rainbow Stones feature a raw, unpolished surface that gives the designs a cool, edgy look. Every stone is unique, so color and brilliance may vary!
