The Greville Ivy-leaf Clips were from the collection of Dame Margaret Greville, the wife of the Hon. Ronald Greville. Margaret and her husband had had no children, and she bequeathed all her jewellery to Queen Elizabeth the Queen Mother upon her death in 1942.
The clips were made for Margaret by Cartier. One of them was made before 1930 when she had a diamond reset, and the other was made in 1937 with stones already in her collection. The first one was also modified in 1937 to match the second one. After Queen Elizabeth the Queen Mother inherited them, she gave them to her daughter Elizabeth for her 21st birthday in 1947.1
She has worn them as hit pins but also as brooches.
