Description: | Medieval gold and sapphire finger ring, 23mm wide and 26mm long. The ring has a sub circular setting 10 x11mm and 9mm deep. It is in good condition and weighs 5.24grams. The setting is circular in form with a slight bulge to accommodate the stone and slightly trapezoidal in section, turning in to hold the stone in place. It has slight collars where the loop is attached but is otherwise plain. The stone is a natural sub-triangular shape, highly polished and is black-blue in natural light. When artificial light is shined on it it is dark blue-green.Non-destructive X-ray fluorescence analysis of the surface of a gold finger-ring from Mowsley, Leicestershire, county, indicated a gold content of 84-87%, a silver content of approximately 9-11%, the remainder being copper. The stone was identified by Raman spectroscopy as sapphire.
