Etymology: The stone takes its name from Chalcedon, an ancient Greek city on the Asian shore of the Bosphorus, opposite Byzantium (later Constantinople, now Istanbul). The Greek adjective "khalkhēdónios" meant something like "of Chalcedon," and Latin borrowed it as "chalcēdōnius." The word is a place-name derivative, the same kind of formation as "Lilliputian" or "Brobdingnagian" in English, in which a locality becomes an adjective for the things found there. The word's deeper roots are less certain. It is cognate with the Arabic "karkand," a name for a stone of this kind, which suggests the trade in such stones ran through the Near East and that the Greek and Arabic names share a common source in an older language. The precise direction of that connection is not something the evidence settles cleanly, so it is best read as a sign of how widely the stone was traded.
