The pediment with a step cut aquamarine with canted corners, estimated to weigh 87.82 carats, within a millegrained surround of eight cut diamonds, approximately 0.76 carats total, suspending a large briolette aquamarine drop, 5.4cm long, with a banded and pierced scrolled rose cut diamond set cap, suspended from a rose cut diamond bale.
The brooch is a stunning 10.8cm in total length and is estimated at £15,000-20,000 (+fees).
Excellent depth of colour
This classic Belle Epoque jewel was made in 1910, it is however unsigned, and was possibly made in either the US or UK. The mounting is platinum fronted gold, the strength of which allows for a minimal, light setting so showing off the aquamarines to their best effect.
These stones are of top gem quality (probably Brazilian) with excellent depth of colour; today aquamarines such as these would be designated ‘Martha Rocha’ in colour. Martha Rocha, left, was a Brazilian beauty queen in the 1950s, and she was known for her brilliant, captivating eyes.

The pioneering Nancy Astor
Nancy Astor was born in the United States and moved to England at the age of 26. She married Waldorf Astor in 1906, and they set up home at Cliveden, the Buckinghamshire estate on the River Thames. She became a parliamentary candidate for the seat of Plymouth Sutton when her huband, the previous incumbent, became a member of the House of Lords. On 1 December 1919 she was the first female MP to be elected to Parliament and to take up her seat.

By direct descent
Viscountess Astor was not particularly known for her jewels, and in paintings and photographs she was invariably depicted in her favourite string of pearls (and, of course, a tiara when attending a ball). The aquamarine and diamond brooch has remained in the family and is consigned to the forthcoming March auction by Viscountess Astor’s great granddaughter.
