Quartz disk jewelry
"Wheels of light" are innovative quartz disks with sealed inserts of colored gems or minerals, creating multiple reflections to lend color to otherwise transparent rock crystal. Inside these examples are Paraíba tourmaline (left) and realgar (right). Photos by Eric Welch; courtesy of Nature’s Geometry.

At GJX, Brian and Kendra Cook (Nature’s Geometry, Graton, California) showed an innovative series of clear quartz disks they call “wheels of light.” These disks are mounted in work-hardened 24K yellow gold for use as pendants or earrings. The center of each disk contains a tube where an insert of colored gem material can be placed. The tube is subsequently sealed with clear quartz. When the disk is viewed face up, the insert’s color reflects and suffuses the disk with bright color (figure 1).
