Tumbaga Gold is the legendary alloy of the Inca and Aztec master‑metallurgists — a deliberate blend of gold, silver, and copper engineered for strength, beauty, and ritual significance. Over centuries, its ratios changed, creating distinct eras of production that collectors and refiners prize today.
Through a secret ancient citric‑acid “pickling” process, artisans could pull gold to the surface, leaving objects gold‑laden, encrusted, and radiant. This made Tumbaga Gold both a functional metal and a sacred transformation ritual.
Today, Inc Gems™ preserves authentic material from these production periods — raw alloys, pickled and un‑pickled pieces, and cultural relics — now available to the public for the first time.
Tumbaga Gold is not just metal. It’s metallurgy, myth, and history fused into one collectible form.
