Gemmology: the search for complete transparency
Our gemmologists travel around the world in search of rubies, emeralds, sapphires and diamonds. With an array of princess, brilliant, marquise, and oval cuts, our precious gems meet the highest standards in colour, carat weight and clarity.
Nearly 30,000 carats of precious gems are set each year in our workshops.
All diamonds are tested according to stringent in-house guidelines. Nothing escapes the scrutiny of our experts at Piaget Manufacture.
Piaget has been pursuing a rigorous ethics and environment policy for several years. The brand only uses diamonds that comply with the Kimberley Process. Each precious centre gemstone is delivered with a certificate. By fully integrating production processes, Piaget maintains total design freedom and is able to produce pieces that reflect the designer's original intent as closely as possible.
