Shell regarded

This glass container - is it too large to be called a jar? - sits atop a cupboard in my mother's kitchen. The contents were not bought, they were collected by hand. Mum gathered the seashells over a number of years when we lived near the beach. One of my sisters and her partner added some more, picked up on another stretch of coastline. The red soil Mum transported home from a trip to central Australia. It's a special object, isn't it?
