Apart from the fact that it has numerous good quality and desirable old European cut diamonds, a proper investigation of the hallmarks could indicate a Faberge workmaster. In that event you are talking big money ie $50,000 maybe or more. Please get the brooch properly assessed and don't go selling it to anyone for a small amount to have them go away and make the big $$$$ because you didn't know any better.
