Siren Tail Earring with Blue and Green OpalsThis flamboyant single earring captures the grace and opulence of a mermaids tail. The earring is designed as an 18k natural white gold tail and is constructed so it gently moves, with its scales dotted with white diamonds. The piece graduates into a sweeping, 18k rose gold fin, designed as three elements to create a slight movement, that gleams with iridescent blue and green opals and tiny white diamonds.
