Decades ago, Zuni artisans perfected inlay jewelry. Mosaics of stones are each individually cut and placed into a silver or gold "frame" for a tight, epoxied and polished fit. Perhaps more surprising is that each piece has a hand-etched locking groove. Micro inlay takes this one step further with tiny, fragile pieces of turquoise, mother of pearl, coral, and peridot intricately connected.
