These earrings were created with silver plated flatware. These flowers are the Arbutus pattern created in 1908 by Wm Rogers & Son. Given as a gift in the 1950's there is no telling how old these earrings actually are. Asking other collectors and sellers no one has come across anything like this. They also contain genuine heishi pearls. They hang from brand new sterling posts and hang just under 2.5 inches.
