Two jewels caught my eye.
The first is the diamond, pearl and ruby necklace.
I wonder which came first? The Cromartie necklace or the one in the exhibition?
The Cromartie necklace (below) was offered for sale by Christie's in 2007.
According to Christie's the Cromartie necklace was made in 1849.
For more information on the Cromartie necklace see
If Christie's information is correct then the one displayed in Paris in 1862 is a copy (but not identical) of the Cromartie necklace.
