A translucent, light to dark brown chalcedony, sard takes its name from the Greek Sardis, the capital of ancient Lydia. Until the Middle Ages it shared the name "sardion" with Carnelian. Bands of sard and white chalcedony are called Sardonyx. Sard forms from the deposition of silica at low temperature from silica-rich waters percolating through cracks and fissures in other rocks. One famous locality for sard is Ratnapura, Sri Lanka. Other source are in India, Brazil and Uruguay. It was used at Harappa, one of the centres of the Indus civilization (c2300-1500BC), by the Mycenaeans (1450-1100BC), and also by the Assyrians (1400-600BC).

MYKU Sardonyx Watch


I bought this watch for my wife as the birthday gift. She hand-picked the stone pattern without knowing that it was for the watch until she received the gift. The watch is unique as there is no another watch would be exactly the same. My wife loves it very much. And thanks so much for Francois 's wonderful shipping and handling arrangement.""
