This piece broke when I cut it and I left it as is and finished it anyway. Part of my broken heart series of mourning jewelry as metaphor. I hand cut focal bead made out of genuine jet from Russia. Measurements in the title. 2.5mm drill hole. CHAIN NOT INCLUDED. I work in a variety of natural jet from around the world but most of it is from Russia or Tennessee. The most famous jet is from Whitby, England but rough material from there is nearly impossible to get. Jet is a kind of gem grade lignite coal that has been used in beads and jewelry for over 15,000 years. It 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.
