Another Seeking advice... this time on a brooch/pendant

I bought a brooch/pendant a few years back, because I was intrigue by the design and variety of objects used to make.
My personal thoughts are definitely vintage, possibly antique from the suffragette period as it incorporates the known colours of purple, green and white, such as amethyst, peridot, pearls and other similar similar. The flowers look like green glass (Green obsidian?).
It is articulated at the bottom piece. Can be worn as a brooch or a pendant with the bail at the back.
I don't know if the gems are real, but I think they could be. The Pearls also look real.
It is engraved/stamped on the rear with ' 925' 'ag' + 2 letters more that I can't read properly

Weighs approx.27g or 1oz,
Stands approx. (L) 8cm (3in) x (W) 5cm (2in)

thanking you in advance for any insights or opinions.
