Easdale is the smallest permanently inhabited island of the Inner Hebrides and is known as 'the island that roofed the world' due to the large amount of slate that was once quarried there and put to use as tiles. The beautiful cubic pyrite that is naturally dotted throughout certain areas of slate caused it to be rejected by the quarrymen, who knew that it wouldn't make good roofing material - doesn't it look spectacular as jewellery though?
