Yes. The picture of the Queen Mother, does show her wearing the Greville Bow Brooch. It has no relation to the ruby and diamond brooch worn by Princess Margaret.
This is the information provided on the Greville Bow Brooch
The Greville Bow Brooch
Boucheron, c. 1900 Diamonds, silver, gold12 x 10 cm In the form of a knotted bow, the borders pavé set, the centres of the pierced bands collet set, with large and small brilliants, original box, stamped: Boucheron - Paris
This unusually large and lively brooch, of sophisticated construction, was probably part of the commission given in May 1900 to Boucheron, the firm that Mrs Greville patronised very regularly from 1899 to 1925. This work, which cost 3,000 francs, involved the dismantling of a knot-pattern diadem and the removal of 718 brilliant and 484 roses, to made a new diadem and a 'noeud Brilliant faisant broche', probably identifiable with this brooch. It was among the spectacular piece bequeathed by Mrs Greville to Queen Elizabeth in 1942, but was not worn often, perhaps due to its exceptional size. The brooch was inherited by The Queen in 2002."

NOTE: The tiara that was made at the same time as this brooch, was the one later dismantled to create 'The Greville Tiara'.
There is a HQ photograph of this bow brooch, however I neither have a scanner, nor want to post photographs from this book.
