The crescent moon inspires imagination & creativity. The crescent symbol often with an accompanying star may have its origins in ancient Babylonia, having its earliest written example found more than 6000 years ago. The earliest hieroglyphs found depicting the Crescent and Star were dated to 4500 B. C. The crescent hanging with points up towards the sun is a Cherokee symbol of harmony.
After each artifact or specimen has been discovered it is sent through a careful restoration process before being used in a design. If a particularly unique patina is found to add design value to an artifact, it's preserved & sealed to ensure its longevity & protection.
