our precious metal jewelry is the result of craftsmanship and industry. Each Le Gram collection combines a specific shape, precious metal, imprint and finish which require all the know-how and mastery of French workshops.

Our precious metals

• 925 silver: 1st quality silver composed of 925 thousandths of silver and 75 thousandths of copper

• 750 yellow gold: 18 carat gold composed of 750 thousandths of pure Gold, 150 thousandths of Silver and 100 thousandths of Copper
• 750 red gold: 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 acquire a patina over time. in the same way 925 black silver will evolve over the use of your jewelry, the treatment carried out will fade in certain places, revealing the shine of untreated silver.
