Victor Mayer Art Nouveau Pendant and Chain

This is from the sellers notes. This piece has his stamps on the back of the pendant and it has been authenticated by the company with the following message. The jewellery item presented in your email was probably made between 1898-1905. We still have in our archives books of all the jewellery items ever made. Unfortunately it would take to much time to make an investigation to find out more. I very much hope for your understanding .

The pendant is silver fired enamel, I love the colours and considering it's over a hundred years old it's in good condition. The design looks very simple, but the more you look at it, the more complicated it becomes. The chain is also marked with his name. I shall put a link on below which tells you about his life, he was a interesting man.
Many thanks for looking
