Jean Christophe wants you to think he's Excessive

Jean Christophe Fouchier, a Parisian jeweler who works as Jean Christophe, has released a new collection of rings, called "Excessive". According to the press release, these are "a cry of hope in the face of our too gray, too urban world". They use bright lines of colored stones, Paraiba Tourmaline for blue-green, Tzavorite Garnet for green and Spessarite Garnet for orange, set in dark flat metal, probably blackened gold.

If you want to grab one in person, he's at 18 rue des Capuchines, in Paris.
