Both the earrings and the makers mark strike me as having art nouveau influences. I wasn’t able to find an online listing of makers marks specific to the art nouveau period. This resource looked like it might be promising though:
Hallmarks and History of Vintage, Contemporary, Modernist and European Costume Jewelry Designers- Research and Information Page: Amazing Adornments.com
the website focuses on costume jewelry, but I’m guessing that the “costume” versus “fine” jewelry may have been more fluid one hundred (plus) years ago than it is today.
there are also several books available on art nouveau jewelry - perhaps you can find one online or in a local library?
