The Queen Mother's Curved Aquamarine Clip Brooches

Queen Elizabeth The Queen Mother had a few pieces of aquamarine jewelry she wore around the 1930s and 1940s, including the Aquamarine Pineflower Tiara now in The Princess Royal's collection, and the Aquamarine Art Deco Brooch now worn by The Queen. She had another set of two aquamarine clip brooches dating from that period, also now worn by The Queen:

These small clips have aquamarines and diamonds and a distinctive curved end shape. The jewels are likely the ones described by Leslie Field in The Queen's Jewels, dating them from at least 1935:

In the 1930s she [Queen Elizabeth The Queen Mother, then The Duchess of York] had a pair of curved diamond and aquamarine clips. She was wearing these in 1935 when she brought her two daughters to Norman Hartnell's salon in Bruton Street to have a fitting for their bridesmaid's dresses for the marriage of Princess Alice, Duchess of Gloucester.

The Queen Mother wore them as a set or individually, on her hat. They were not among her favorites in her later years.

The Queen inherited these brooches along with the rest of her mother's jewels and possessions in 2002. She's just debuted them now (November 22, 2016), on a suit she usually pairs with the Aquamarine Clip Brooches that she received from her parents for her 18th birthday and which have been favorites ever since. A little more aquamarine variety in her collection can't hurt, right?
