The silver article is a decoration made of a silver metal body (or silver alloy body) or a silver decoration body such as in the form of a sheet. After the silver metal body is formed, at least a part of the surface of the silver metal body is heated to a recrystallization temperature to form a recrystallized surface layer. Accordingly, the residual stresses of the silver metal body are eliminated and the malleability thereof is enhanced. The crystalline grains of the recrystallized surface layer can regrow to present the specific qualities of cubic lattices. The recrystallized surface layer can be further processed by fine electrolysis to enhance the clearness and brilliance of the recrystallized surface layer.
