George IV of the United Kingdom
There are conflicting reports about what happened to the diamond during these years. Eliason's diamond may have been acquired by George IV of the United Kingdom, possibly through Caroline of Brunswick; however, there is no record of the ownership in the Royal Archives at Windsor, although some secondary evidence exists in the form of contemporary writings and artwork, and George IV tended to mix up the Crown property of the Crown Jewels with family heirlooms and his own personal property.
