J.Grahl Design (Pearls)

Thank you for this photo of the set which is much better than the previous similar photo in this thread The Art and Jewelry of J.Grahl Design - #4 by JimGrahlDesign

It looks like this photo has more light, which clearly shows how the rose gold wire in the perforation of the Lalique beads looks like fire in the opalescent glass.

Are the tiny enameled beads also made from rose gold? Are the ear hooks also made from rose gold?

Even though I know the glass enhances the color of the metal in the perforation, the ear wires look so much darker. Is there a patina on the rose gold?
