Sixteen-by-seven-millimeter blue Kingman turquoise with 3mm spiny oyster shell sterling silver earrings - the Southwest earring pairing the distinctive Kingman blue with the vivid color of Pacific spiny oyster shell. Kingman turquoise from the Arizona mine carries a characteristic medium blue with matrix patterns specific to the Kingman deposit. The 3mm spiny oyster shell rounds provide warm color accent. Together they create a Southwest earring in the warm-cool material dialogue that is the visual signature of the regional jewelry tradition.
