WM Co. Sterling Concho Earrings | Spiny Oyster Shell Southwern 1970s

Striking vintage dangle earrings stamped WM Co, attributed to Wheeler Manufacturing Company, a Southwestern jewelry house active from the 1940s through the 1980s, with workshops in Lemmon, South Dakota and Albuquerque, New Mexico. Their hallmark WM Co. is linked to a long history of handcrafted silver pieces reflecting the artistry of the American Southwest. These earrings feature deep orange cabochons set in radiating concho frames with three feather dangles each—classic Western styling with bold, wearable charm. Although some listings have labeled these as “amber,” the visual characteristics—such as the natural grain, fine streaks, and subtle fibrous banding—are more consistent with spiny oyster shell, a material traditionally used in Native and Southwest jewelry. Spiny oyster shell ranges in shades from coral red to orange and was commonly incorporated in jewelry from this region and era. ✦ Sterling silver, marked "WM Co" ✦ Circa 1970s Southwestern design ✦ Bright reddish-orange cabochons (believed to be spiny oyster shell) ✦ Concho shape with detailed feather dangles ✦ Total length: approx. 2 ¼" ✦ Lightweight and statement-worthy 📦 Ships securely in a new jewelry box within a padded package 🚭 From a smoke-free home 📷 Photos taken in LED lights - unedited
