This is a diamond and precious metal brooch worn a few times by HM in the last couple of years. It is an arched spray of 2 (what I know as) old-fashioned roses and one, still closed bud. The petals appear to be made of rose coloured gold and it may contain some coloured gems as well but it is hard to tell. To the best of my knowledge, the provenance of this brooch is not know...but if anyone knows any more, please share. Cheers! Bryce
