An antique gold, silver, diamond and pink topaz stomacher, early 19th century. Part of the House of Hohenzollern Royal Pink Topaz Parure. The top element set with a large rectangular cushion-shaped topaz within an old-cut diamond openwork border, with the sides emphasised by curvilinear diamond motifs, attached to an ornamental centre of diamond and topaz scrolls and ivy leaves terminating in a pendeloque topaz within an old-cut diamond border.
Platinum millegrain brooch centred on a carved emerald representing a tree on a pave set diamond trunk, with eight small diamonds in single collets between the leaves and a triangular cut diamond at the top. Two birds, with sapphire heads and tails, emerald legs and bodies and ruby wings, their heads turned backwards flank the tree, beside navette shaped emerald plants, all resting on a triple baguette cut diamond base. Cartier, London, c. 1935
