84mm x 46mm. From the collection of Bryan Kennedy.
This agate is one of the finest I have seen from the location, and is definitely the best large blue-grey agate from St Cyrus that I know of in existence. It is very like the larger stones found at Barras Quarry, Hats off to Bryan for finding it. I was honoured to have the pleasure of revealing it to the world.
