Denim Lapis Gemstone Beads. Usually speckled with iron pyrites, Denim Lapis is a soothing, soft blue. In the past, it was often made into vases and bowls, and has been used for thousands of years for beads and small ornaments – and actually was known as the “sapphire of the ancients,” because of its use in mosaics. Tenderness, sympathy, are the attributes it supposedly represents. We carry a variety of sizes and styles of Denim Lapis gemstone beads for your jewelry design needs.
