Black Stone gemstone beads, 8mm round smooth matte with a pattern.
Not sure the stone, I honestly can't remember :) but its a stone.
De-stash from my personal supply collection.
All my gems were carefully chosen with the intent to become beautiful pieces of jewellery one day, but as I continue to collect stones and change my design style, many stones become not suitable for my work. Take advantage and get yourself some beautiful gemstones to create your own jewellery.
