The Cambridge emeralds have an interesting - and slightly juicy - past. They get their name from the Duchess of Cambridge - not the one we know today but Augusta of Hesse-Kassel, Queen Mary's grandmother. Augusta and her husband Prince Adolphus, the Duke of Cambridge and one of the sons of King George III, entered a lottery for charity on a stop in Frankfurt and won. Their prize was a box of cabochon emeralds (which according to some may once have belonged to Indian royalty). There are conflicting sources on the exact number of emeralds in the prize, but between 30 and 40 is probably most accurate.

Naturally, Frank's sister Queen Mary did not approve. She had Frank's will sealed, presumably to avoid a scandal just before she and her husband were to be crowned. (This became standard practice for royal wills from then on.) And she set about getting those emeralds back - because not only was she a magpie, she was a true lover of the family history and meaning behind her jewels. And family heirlooms leaving the family by way of the mistress, one can imagine, would just not do.
The tactics used by Mary to obtain jewels and other precious objects are often exaggerated (and sometimes not...) and sure enough, stories of social exile and so on for Ellen Constance can be found when it comes to Mary obtaining the Cambridge emeralds. It seems to me stories either go for the gossip or gloss over the awkwardness of the situation, simply stating that Mary "acquired" the emeralds. At any rate, Mary paid the Countess £10,000, a considerable sum which amounts to somewhere around £800,000 or more today. And she ended up with her emeralds.

With the Cambridge emeralds in hand, Mary set about creating a parure for use at the Delhi Durbar. These pieces were added to with a few gifts given from Indian groups. Mary wore the whole parure at the Delhi Durbar, and continued to wear it for the rest of her life. She did alter some pieces as time went on, as she was prone to do. The whole parure is now with the Queen, almost all of it having been inherited on Queen Mary's death in 1953.![]() |

The emerald pendants are Cambridge emeralds. This is the tiara the Queen would use today to cap the parure, and was used with the emeralds by Queen Mary in her later years.
The Delhi Durbar Tiara
This is the original tiara belonging to the parure, and was initially topped with Cambridge emeralds. Those emeralds today hang from the Grand Duchess Vladimir Tiara, though at one point in time they were also used as uprights on a diamond bandeau tiara inherited by the Duchess of Kent (which can be seen by clicking here). The Delhi Durbar Tiara is in the Queen's collection, but was last worn by the Duchess of Cornwall.
