The long lampwork bead in this necklace is a creation by Maine artist, Rhonda Madden. It has beautiful wavy swirls of green and maroon. I teamed it with a pyramid cut blue chalcedony gemstone. The bezel on the chalcedony is fine silver and all of the other metal work is sterling silver. It comes with an 18" sterling silver box chain. This is a great year round necklace. The dimensions are 3 1/4 x 3/4".
