Le Gramme

Le gramme is a brand of jewellery for men and women where each object is named by its weight in grams. The creations le gramme draw their strength from their minimal form, from an obviousness in repetition, from the free field they open by their capacity to accumulate in order to create their own language. Le gramme's collections come from a creative process inspired by industrial design and are rationally thought: the shape emanates from a reflection in the absence of drawing, until fulfilling its function. then the object is realised.

Brand designer

Erwan Le Louër

Co-founded in 2013 by Erwan Le Louër, who holds a master's degree in industrial design from the esdi 2008, a graduate school of industrial design, le gramme is the latest concept launched by the designer-entrepreneur. After a first entrepreneurial experience in 2008, through the launch of the jem jewellery brand and at the same time in charge of the maison margiela jewellery license until 2011, le gramme becomes a new form of transmission of erwan le louër's passion for aesthetics and the central place of the object in his life. An elementary form, a noble material, an imprint and a finish, the objects le gramme embody the culmination of his creative vision. A vision that is also expressed, since 2010, in the constitution of a private collection of contemporary art - the archives project - which aims to build a guideline of minimal aesthetics and taut lines, with the uncompromising rigour of a collector passionate about the absolute creative gesture.

Jewelry production


Our precious metal jewellery is the fruit of craftsmanship and industry. Each collection le gramme combines a shape, a precious metal, 750 gold or 925 silver, a specific imprint and a finish that require the full mastery of our french workshops. 'Made in france' was an obvious choice when we launched le gramme in 2013, due to its exceptional jewellery know-how and our desire to export it internationally while adhering to a sustainable approach. As part of our development, with increasing production, some of our creations have been manufactured in germany. France, known for its high precision in this field, its machining techniques and its know-how, brings together all the human and technical qualities required to manufacture the jewellery le gramme.

Our precious metals

Yellow gold 750 : 18 carat gold composed of 750 thousandths of pure gold, 150 thousandths of silver and 100 thousandths of copper. Red gold 750 : 18 carat gold composed of 750 thousandths of pure gold, 40 thousandths of silver and 210 thousandths of copper. Our collections are made of untreated 925 silver and 750 gold in order to develop a patina over time. In the same way, the black 925 silver will evolve with the use of your jewel, the treatment carried out will fade in certain places, revealing the brilliance of the untreated silver.

Pattern and finish tags

The jewels le gramme are always characterized by an imprint and a finish. Each variation has an identity imprint : slick pattern for permanent variations; engraved or guilloché-print for temporary collections; our finishes can be " polished ", " brushed " or " mat ", they enrich each object with a new relationship in the light : "polished" or "brushed" finish tag for the slick pattern tag, polished" or "matt" finish tag for guilloché pattern tags, polished" or "brushed" finish tag for engraved pattern tags.


Le gramme is a creative project based on the object and its weight. All our creations are named by their weight in grams, a weight whose number is systematically odd. Please note however that for small and large sizes, for rings as well as bracelets, a slight difference in weight can be observed. Indeed, for these sizes which require more or less precious material, the real weight engraved on your jewel can be higher or lower than the name of the creation.

Stamps and engravings

Each piece of jewellery le gramme wears the following punches and engravings: the maker's mark guaranteeing the place of manufacture; the state stamp certifying the quality of the metal précieux: eagle's head for gold and minerva's head for silver; the hallmark le grammesigns the original creation of our brand; 925 or 750 certifying the purity of the precious metal; the logo le gramme; the batch number which guarantees the traceability of the object's production; the weight of the object in grams.
