The brooch is in very good condition with no signs of damage, heavy wear or repair. The principal diamond is estimated to be J colour and Si2/I1 clarity. Some light nibbles to the girdle. The centre of the stone is clean. There is a white translucent inclusion under the crown by the girdle to the top left edge. Some light bearding to the girdle throughout. Light scratches to the platinum and gold throughout, commensurate with age.
