The regular sized mosaic puzzle piece pendant measures 1" x 7/8" and features individual pieces of Dichroic glass which are layered and fused in hues of different colors to create this unique look. Each piece is suspended from hanging loop to put around a necklace (not included). Due to the rainbow-like properties of the glass, colors and patterns will vary. No two are ever alike! These beautiful puzzle pendants are handcrafted in the USA by glass artist Janine Stillman. All purchases donate a portion to an autism organization. They are a beautiful and fashionable way to show your support for autism and help raise awareness.
