Teal and Brown Chunky Stretch Bracelet

Not sure what these beads are made of (lucite? plastic? resin?), but the bracelet is fabulous! Teal with patches of ivory with swirls and swatches of brown throughout, looking almost like a butterfly wing. Bracelet measures about 8.5 inches on the outside, 6.5" to 6.75" around the inside, and stretches well.
