Description: | A medieval gold stirrup-shaped finger-ring. The slender hoop rises to a pointed bezel, which is set with a small blue stone. Non-destructive X-ray fluorescence analysis of the surface of the ring, carried out by the British Museum Department of Conservation and Scientific Research, indicated a gold content of 70-74%, silver content of 14-16%, the remainder being copper. The blue stone was identified by Raman spectroscopy as corundum. Corundum with a blue colouration is known as sapphire.
