I found some images of Sita Devi of Baroda wearing the stunning black pearl bracelet which I thought others might like to see. It is a great shame that none of the photos is in colour, especially the 1958 photo of her with Harry Belafonte.

The bracelet. Image is from Christie's as per the link.

Only part of the bracelet can be seen in this 1960 photo.
