The Queen's Single Strand Pearl Necklaces

A collection of pearls as rich as the Queen's obviously has single strands to go along with the two- and three-strand necklaces. As with the other necklaces, it can be difficult to determine if the strands are different or the same over multiple appearances. It is also possible to wear multiple single strands, creating the look of a multi-strand necklace, obviously.

One option is this single strand worn on its own. This is a more informal look for the Queen these days, and is not spotted as often in public.
