I hand cut this freeform style focal bead made out of genuine jet from Russia. Polished finish. Measurements are in the title in millimeters. 2.5mm drill hole. Comes in a gift box. I work in a variety of natural jet from around the world but most of it is from Russia or Tennessee. Jet is a kind of gem grade lignite coal that has been used in beads, jewelry, carvings and ornament for over 15,000 years. It's a true fossil fuel jewel. Jet reached its biggest popularity during Victorian times as traditional mourning jewelry. For this reason it is still associated metaphysically with alleviating grief and depression. It is also said to help with financial stability. See other focal beads, cabochons, and more in my DVHdesigns store!
