This glossy, iridescent conical shell comes from the trochidae family. The exterior of the shell has been polished away to reveal this mother of pearl layer, which is called nacre. This inner shell layer is made by some molluscs and it is also the material that pearls are made of.
These typically measure from 5cm to 7cm high. Colours and sizes will vary; these are natural shells and the photograph is of a typical example, not the shell you will receive. If you have any particular requests in terms of colour or size, please pop them in the notes - we’ll do our best to find the shell that comes closest to what you want!
