This beautiful focal bead was created using a silver enhanced glass. It has waves and streaks of lavender, blue and yellow. Unfortunately it's difficult to photograph.
It measures approximately 30mm diameter x 15mm thick and was created on a 3/32" diameter mandrel.
All my glass beads are handmade by me in my studio and are properly annealed in my digitally controlled kiln. They are carefully cleaned & inspected for flaws.
