Lab-Created Dark Opal | Blue | Smooth Cabachon | H1902G

This lab-grown opal cabochon offers a multicolor presentation that's a beautiful and affordable alternative to genuine opal in a wide variety of jewelry designs. This material is created from very uniform nanoparticles of silica dioxide and water—the same makeup as naturally formed stones. The play of color in each stone is produced by light refraction just as in genuine opal; no dyes whatsoever are used. Use single stones in earrings rings or pendants or take advantage of the price point to create a complex multi-stone design. Opal is one of the birthstones for October.
