Camogli Stones

I'm working on my new series of drawings 'Camogli Stones'. We hung out at Camogli in Liguria, Italy this summer and I was mesmerised by these stones on the beach - in the water they sparkled and glistened, with the richest deep green and black colours. When dry, they revert back to their more subtle greys with white streaks and pale green markings

I've spent hours at home drawing them in bright sunlight.
