Gladys and Charles Mumford Silver and Amethyst Brooch

Another Glady and Charles Mumford piece. I think this brooch was made in the 60s I'm not certain, that's for sure, but it does have a coiled wire on the bottom of the stone at the back, which I haven't seen in their earlier pieces. Same as the ring a very distinctive leave and scrolls and coiled wire design. The design is very simple but effective you can tell there work almost anywhere.
Here is a little piece about them, there is precious little information about their life that I have found.
Gladys and Charles Mumford had their workshop and retail outlet in Falmouth, Cornwall. They had previously started their careers as Silversmiths to Winifred King & Co in Coventry. They moved to Falmouth were they also sold their Jewellery on board QE 11 (Queen Elizabeth second). The work of Gladys and Charles Mumford was rarely if ever marked.
Many thanks for looking
