This brooch has been made from a polished disc of Paua shell.
The shell is from New Zealand where most of the Worlds Paua shell is found.
This isn't actually a fossil, but a modern shell but I thought  someone might like one anyway!
The shelll has a super variety of colours and a lovely shimmer when it catches the light. 

The brooch measures 2.5cm and is nicely boxed and labelled in a padded, velvet lined box.

( This may not be the exact same brooch you receive but will be very similar in appearance and size.
These are natural objects and all unique - so you will really will get a true one-off!)
