Vintage Native American Sterling, Coral and Turquoise Ring, Signed, size 5.5

Vintage Native American Sterling, Coral and Turquoise Ring, size 5.5. Signed WMD. It's in a traditionally styled flower and feather design, about 1.5" long so it's very eye-catching. Acid tested as sterling silver. The turquoise stone is either cracked or has a natural fissure but it doesn't take away from the beautiful silver work.
