 With his new status, the King ordered new regalia to be made, which included the Wittelsbach Diamond, an oval Old Mine cut blue diamond.The diamond's history dates back to the 1660s and for the most part has been uneventful.The gem was offered with other Bavarian Crown Jewels in a 1931 auction at Christie's in London, but apparently it did not sell, nor did it return to its display in Munich.
