Estate Antique Victorian Gold Marked Etched Enamel RMR Intialed Bangle Bracelet

Very beautiful etched and enameled gold filled (?) bangle. Has original catch chain and closes very strongly for age. Nice floral etching with initials RMR. The flowers have black enamel. I could not see a makers mark. However the inside part of the clasp is marked 1/20 10K.
