Doreen, Lady Brabourne's spectacular diamond tiara, was designed as a series of diamond-set geometric panels to the central oldcut diamond penant and quatrefoil cluster, which was detachable to form a brooch.
It was probably made in 1925. For Lady Brabourne, some sketches and drawings of the time for variation of the tiara are known.
The art deco diamond tiara was sold in the year 2002 from Christie's.
To match the tiara, Lady Brabourne owned a suite of magnificent diamond art deco jewels>> .
He married Lady Doreen Browne, daughter of the 6th Marquess of Sligo and their second son [7th baron] married Lady Patricia Mountbatten.
The diamond ear pendants are probably later worne from Lady Patricia Mountbatten - Knatchbull on the occassion of the wedding of Princess Margaret of Great Britain in 1960.
