I hand cut this dog tag style focal bead made out of genuine jet. Natural satin matte finish that will get shinier the more you handle it. A polished finish would get scratched over time but a matte finish will look better! Measurements are approximately 45x25x5mm but each piece is hand made and dimensions will vary slightly. Group shot is to show variation, listing is for QUANTITY 1. 4mm drill hole. 24" nickle plated steel bead ball chain included, 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!
