This chunky gemstone is called Larimar, named after the ocean and you can see why! 
The large pear shaped stone is set in recycled sterling and is on a hammered band which represents the ripples of the ocean. 
Larimar is only found in one place in the world, on a beautiful Caribbean island renowned for great surf, kitesurfing and diving conditions, so take a piece of the Caribbean with you! 
This is a U.K. size R 1/2
