There has been some debate about whether or not this brooch - part of the Greville inheritance - oft worn by Queen Elizabeth and now worn by the Duchess of Cornwall, has an interchangeable central stone.
There is definitely an emerald - the debate is whether or not the stone can be interchanged with an amethyst (or perhaps a sapphire).
