Mourning jewelry made from genuine jet! Jet is a kind of gem grade lignite coal that has been used by humans for carving and ornament for at least 15,000 years! My rough material comes mostly from Russia & Tennessee. I may have an occasional rare piece from the classic source in Whitby, England where most Victorian mourning jewelry was made in the 19th century. We are living in a carbon fossil fueled society but most people have never even touched a piece of REAL coal. Charcoal is manufactured from wood products today, it's not a fossil fuel. Nearly ALL of our energy and prosperity over the last 150 years has been due to the burning of fossil fuels. It is time we stop burning this sacred material and start honoring and revering it and it's spirit.
