our precious metal collections are the result of precise craftsmanship and an industrial know-how. each le gramme collection combines a shape, a precious metal, 750 gold or 925 silver, a specific imprint and a specific finish that require all the mastery of our french workshops.

When we first launched le gramme in 2013, made in France was an obvious choice for our brand because of the country's exceptional jewelry-making know-how. Our vision is to export our technical excellence globally while adhering to our sustainable approach. With increasing production, some of our creations are now being made in Germany.

France, which is known for its great precision in this field, its machining techniques and its design know-how, has all the human and technical qualities required to manufacture le gramme pieces.
