Can you spot the “real” turquoise? The ring, while “Zuni” style, contains plastic. The bracelets and ketoh blend actual stones and an early “fake” turquoise referred to as “Hubbell glass,” a coveted substitute in its day. Bits of Hubbell glass were sometimes incorporated into traditional clamshell and turquoise necklaces, providing bright blue accents. Photo by Kitty Leaken.
