Apart from the grand floral tiara Lady Ravensdale wore to the coronation in 1937 and throughout the Season that year, she was photographed wearing other tiaras. I suspect that two of these would be classified as costume pieces, although at least one of these might have contained real gemstones.
The tiaras in the images below perplexed me until I found several reports that Lady Ravensdale had ordered tiaras from Beatrice Dawson.
1933.
Beatrice Dawson created fashionable jewellery from non-traditional materials, which allowed fashionable ladies to accessorise their outfits in a playful way
not possible with fine jewellery.
Ad for Beatrice Dawson jewellery in 1932.
One contemporary reaction to Beatrice Dawson's jewellery commented that it was made from "rubbish".
By late 1934 Lady Ravensdale was collaborating with Beatrice Dawson. I would love to see a photo of this "tiara"
Then in 1935 came these reports.
Throughout 1935 Lady Ravensdale was photographed wearing some very different tiaras. I have no definite proof as yet, but I suspect that these are possibly Beatrice Dawson creations. If so, then I suspect, based on the descriptions in the media, that the first one contains the topazes (or citrines according to some papers)
April 1935
1939
The second tiara, which might contain paste emeralds is this.
March 1935
There are several reasons why I think these emeralds are paste, not the least being this report from 1934.
It is possible that the emerald and diamond necklace which press reports stated provided the stones for the Dawson tiara might have been one Lady Ravensdale was reported to have worn in 1927.
