History of Famous Jewels and Collections: Re: Georgie, Lady Colin Campbell

I do wish I was able to identify the bejewelled ladies in the video, but unfortunately my knowledge is rather limited when it comes to the noble families in the United Kingdom.

As for the date of this State Opening of Parliament, I actually think it might be even 1976. There are two photos on Getty Image where the Queen is visible when searing for "State Opening of Parliament". The date, however, is not accurate as they are both dated 1st January 1975. I suspect that the one which is an overview of the scene is from 1974. In the second one - which is a photo taken closer up - the Queen is wearing a different dress but still with the Baring rubies. So I suspect that is the correct one from 1975.

In 1976 a portrait photograph was taken of the Queen on the day of the State Opening of Parliament that year and she now seems to be wearing the same dress as the one she wears in the video. Also, she is in this photo wearing Queen Victoria's Jubilee necklace.

I know that this doesn't help in identifying the non-Royal ladies, but I thought it worth mentioning as it is so difficult to match the dates when photographs are dated incorrectly or not adequately.

The state openings of Parliament took place on March 12 1974 when the queen wore day dress and no jewels, another grander ceremony happened on October 29 when QEII wore the Baring Necklace. The next year she wore on November 19 the Jubilee necklace as she does in the video posted and the dress matches so I suspect that this was 75. The problem is that Georgie married Lord Colin on March 23 1974 and broke up with him nine months later which would be December and then divorced him n spring summer of 1975 the lady cannot be her as they were divorced by that time.
