SOLD! When it comes to spiney-oyster shell, why settle for the rest when you can wear the best. A diver who used to bring dozens of burlap bags stuffed with spiney oyster shells to Kayenta, Arizona to sell to the Navajo in the Safeway parking lot there, told me that the shells are white in shallow water but gain their colorful hue at greater depths—farther away from the sun. Orange shells start about 40-feet deep, and the more expensive and harder to attain purple shells occur much deeper. Somewhere in between the depth where orange shells are found and the depth where purple shells are found, there is a fine line where the hue is neither orange nor purple, but rather a deep, rich mahogany color—like the earrings pictured above. We think they are a cut above the rest. They are a little over 1.25-inches long and .75-inches wide. Each earring weighs 8.1-grams, or .28-ounces, and each earring is hallmarked.
