This rondelle is fancy with its gold rim top and bottom. The green is a lovely, deep yet transparent green. The rondelle is 7 mm from top to bottom and 10 mm at the widest point. I will say, it does look a bit like a flying saucer. The bead chanel will accommodate up to a 0.5 mm thread. The bead is vintage Czech glass made in a mold in the early 1980s. Price is for 10 beads.
