These beads are LARGE.  They are available either on freashwater pearls $185, or leather thonging $65.  They show a cherrful mermaid with friends, clown fiah, jellyfish, seahrses and turtles.  In the background are coral fronds and below the merry crew are shells.  To add an extra sparkle and depth I have placed dicroic glass at the heart of the bead,
