PLEASE NOTE: THE BLUE JOHN HAS A LARGE CHIP - READ BELOW FOR MORE DETAILS. DESCRIPTION: A lovely vintage sterling silver and genuine blue john gemstone ring. Blue John is an extremely rare mineral and can only be found in Derbyshire in the UK, it is in fact Britain's rarest mineral. The ring sizes at approx. UK N or US 6.5, weighs approx. 2.01g and is fully hallmarked for sterling silver, dating to 1989. PLEASE NOTE: The Blue John is chipped at near the purple edge, therefore there is a section missing (see pictures/video). It's also rubbed on the face. I've reduced the price accordingly.
