Bakelite Silver Pendant

I've been watching this pendant for a while, the asking price was a little high, it started to lower than I decided to ask the seller what would be their best offer to sell, we came to an agreement.

To be honest it has me a baffled because the silver leaves in my opinion are the work of Bernard Instone, my problem is I've never seen work of his with Bakelite, which I may add is a large piece, I'm still scratching my head about it. I've looked online but found nothing, it's a puzzle maybe it might have been a one of. When I first received it to be honest I wasnt sure about it, I've changed the chain and it looks completely different. I would love to hear what you have to say, and whether you think it could be Bernard Instone, the pendant is very well constructed.

Many thanks for looking
