Here are four short rephrasings that start with Shiny pearls:
- Shiny pearls begin when a tiny grain of sand slips into an oyster and the oyster coats it in shiny layers.
- Shiny pearls form when sand gets inside an oyster and the oyster covers it with smooth, glossy layers.
- Shiny pearls start as a speck of sand inside an oyster, which wraps it in many shiny layers.
- Shiny pearls grow when an oyster traps a grain of sand and keeps adding glossy layers around it.
