Today, Queen Saleha of Brunei celebrates her birthday. As the wife of the Sultan of Brunei, Saleha has a rather incredible jewelry box. We don’t know much about the provenance of most of her jewels, but we can certainly admire their sparkle. To mark her birthday, here’s a look at some of her glittering royal appearances.
