Offering bundles are a feature often seen on Zuni animal carvings consisting of minerals and shells tied to the main carving. Sometimes offering bundles are an aesthetic and creative choice, a gift of gratitude from the carver to the spirit of the animal for the medicine that animal has to teach. The gifts are represented in different ways, sometimes a carved arrowhead, a decorative inlay or even a little offering necklace as seen on Cheryl Beyuka's Silverado jet feathered friend. This songbird (perhaps a Raven or crow) has coral eyes and an exquisite offering necklace from fresh water pearl, lapis lazuli, coral, turquoise and jet beads. Silverado jet is a mineraloid with pyrite inclusions giving it an alluring lustrous quality and a unique place in the jet family. Jet is a compact fossilized black coal. About 4 1/2" long, 2" wide and 2 1/8" tall.
