Marks on Art Deco Bracelet by: Anonymous
Hi Jeannie, thank you for writing in with the following hallmark question:
"I have a beautiful enamel and silver art deco bangle barcelet. I have searched and searched to try and find the mark. I am in hope that you might know. It also has italy on the bracelet. Thank you have a nice day. Jeannie"
The bracelet sounds gorgeous! If you appreciate enamel work on jewelry, take a look at the French antique enamel pendant featured on Jewel of the Month.
