Thankyou for the great pics Arthur, it has been nice to really get a good look at this brooch. Regards the black or milky opals, I am not an expert so really have no idea, growing up I always thought, the ones with the whitish background were milky opals & the others with dark blue/green etc black opals but recently looking at those ads for opals I realized I could be wrong. I think the main thing about the Queen`s brooch is they are Australian opals! It really is a very pretty brooch when you can see it properly with the gold gum leaves & diamond dew drops. : : : : : : : :
