The Portrait of King James I
"On 9 July 1929, the Treasurer, Arthur Hill, presented the Company with one of its most treasured possessions, a portrait of King James I. Very little is known about the provenance of the painting, but it is thought to be contemporary.

"The King attached great symbolic importance to the jewels which he wore in his hat. In this portrait he is wearing a setting of three diamonds and one huge ruby which he commissioned in 1604 and which was known as 'the Mirror of Great Britain'. Another great diamond known as the 'Sancy' diamond hangs as a pendant.
