Bernard Instone Silver Earrings

These are a pair of Bernard Instone Silver Earrings. I'm thinking it might be his earlier work. They are clip on earrings, at the back they are marked Silver, BI Made in England. I have looked on many sites but not seen anything remotely like these pair. The flower is a gold colour, so I'm thinking silver gilt, the leaves are plain and are a silver colour, it compliments the gold flowers. They are very simple, but elegant.
Many thanks for looking.
