Augustin Colomer (1893-1973) of Llucia street in Perpignan, played a central role in a social and creative life of Perpignan. He founded the Chamber of artisans and mastercraftsmen mutual association in 1927.
One of the founders of the chambre of vocational occupation in 1930, he participated in the international exhibition of 1937 in showing garnet masterpieces, like the Castillet and the basket of flowers. In Llucia street, the Colomer house represents a key stage in the evolution of garnet jewellery in Perpignan.
