Platifina, the exclusive precious metal jewelry, the creation of Roberto Martinez, is tarnish-resistant and distinguished by a rich, white luster. It is comprised of 3.5% platinum, 92.5% sterling silver and a patented alloy. Inspired by international culture and years in the making, Platifina is an exciting new alternative to sterling silver and other white metals. The jewelry in this line is long lasting in both the nature of its material and in the quality of its design. The name derives from the Spanish "plata" for silver and "fina" for fine.
