A touch of luxury. The name "marble" comes from the Greek word "mármaros", which means "shining stone". The history of marble dates back to ancient Greek and Roman art, where marble was used for sculptures and architecture. With its distinctive texture and coloring, marble provides a particularly aesthetic appearance that makes our watches and jewelry made from this stone very special statement pieces.
