Sparkling jewels and watches offered in Dix Noonan Webb's spring auction A beautiful amethyst rivière necklace. LONDON .- A beautiful amethyst rivière necklace, formerly the property of Marie-Louise, Countess Manvers (1889-1984), will be offered by Dix Noonan Webb in their live/online auction of Jewellery, Watches, Antiquities and Objects of Vertu on Tuesday, March 16, 2021 at 1pm. Marie-Louise Countess Manvers was an acclaimed artist, (painting under the name Marie-Louise Pierrepont). Born Marie-Louise Roosevelt Butterfield in 1889, she was the only child of Lord Frederick and Lady Butterfield of Cliffe Castle Keighley, Yorkshire. In 1917, Marie-Louise married Captain Gervas Evelyn Pierrepont (1881-1955), the sixth Earl Manvers JP MC & Duke of Kingston on Hull. The necklace, composed of large graduating oval mixed-cut amethysts, is estimated at £1,500-£2,000. On her death, the necklace passed to her only surviving child, Lady Frederica Rozelle Ridgway Pierrepont (1925-2015). During the Second World War, Lady Rozelle joined the Wrens and she saw the effects of the war close up, as the wounded were brought home across the Channel. She was particularly moved by the condition of German prisoners of war, remembering: I suddenly became aware of the indescribable tragedy and horror of war. These were no proud and noble specimens of the Aryan race but a pathetic collection of underfed, tired and ill-looking youths wearing the ragged remains of their uniforms, with a forlorn and hopeless look in their eyes.
