A Mermaid Exploring a Cave Treasure
Inside a calm sea cave, a ponytail-wearing mermaid examines a stone tray loaded with different seashells and a natural pearl. Underwater caves often collect natural treasures washed in by gentle currents over many years.
Formation of Ocean Pearls
Natural pearls form inside mollusks, such as oysters and clams, when a tiny irritant gets trapped inside the shell. Over several years, the mollusk coats the particle with layers of smooth nacre, eventually creating a round, shiny gem.
Natural Colors of Sea Pearls and Shells
- Natural pearl: Iridescent white, pale pink, or silver-cream
- Stone tray: Dark gray, charcoal, or slate
- Underwater cave walls: Deep gray, brown, or muted blue-green
- Assorted seashells: Ivory, peach, tan, or coral pink
