Top-seller was an early 20th century jabot pin with twin clusters of central cushion-cut 2ct diamonds each surrounded by 25 smaller graduated diamonds.
With minor chips and soldered repairs, the 2in (5.5cm) long pins, pitched at £5000-7000, sold to a UK private bidder at £16,000.
Also selling well above hopes was a 1920s ring comprising a cushion-cut emerald within a border of rose-cut diamonds and further emeralds,
It was in worn condition with some abrasions and chips but the central stone was of good transparency and strong colour saturation and the ring, estimated at £4000-6000, sold to another private buyer at £14,000.
The jewels had been favourites of Rachel Severne (1933-94) who, as Rachel Fitzgerald, daughter of the Knight of Glynn, had been a famous model known as The Swan.
After marrying Michael Meysey Severne she helped him restore Shakenhurst Hall at Cleobury Mortimer when he inherited the family estate dating back to the Domesday Book.
The house and estate, out in trust for their grandchildren, were sold for a reported £16m in 2016 and some of the contents are now being sold through a series of sales at Bellmans’ Billingshurst rooms.
Chaise longues pair
The 46 lots at the August 2-4 sale included fine art and furniture as well as jewellery.
Topping the furniture were two Regency faux rosewood and parcel gilt scroll-end chaise longues.
Described as a matching pair but sold separately, the 6ft 1in (1.85m) wide chaises were estimated at £600- 800 (about triple what three other Victorian examples fetched).
Illustrated here, the first offered sold at £4200 and the second, with different upholstery, made £3200. Both went to the same London dealer.
