Earrings.
First I have to confess that I cannot see some of the images which Mauriz posted. There are 2 images under the Girandole section which I cannot see, no matter what technique I use.
I find the girandole earrings worn by Irene, Lady Ravensdale interesting. According to the press reports from the late 1920s, she favoured large earrings.
In 1927 one report stated
Then in 1929 came this report
I wonder if that report referred to the earrings in the photo Mauriz posted?
Photo posted by Mauriz.
If so, it is possible that these were fine quality eighteenth-century paste.
1932 report on Lady Ravensdale wearing paste earrings.
I think it is also possible that the earrings seen in the photo below (which was published in 1933) are also eighteenth-century paste.
The earrings which Lady Ravensdale wore when dressed as Catherine the Great (which Mauriz posted) are, as Mauriz said most likely to be set with genuine gemstones. She wore them over a long period.
There is another set of earrings which were seen frequently. They had a set of double drops. I have no idea what gemstones they contained.
I think that the earrings seen in the images below are different from the Van Cleef and Aprels ruby earrings which were auctioned.
Another set??
I very much doubt if this set of earrings were fine jewels.
