Old Stock · Lima, Peru · Natural · One of a Kind These remarkable Peruvian Gem Silica slabs originate from historic copper mining operations in Lima, Peru — material known for its rich gem & mineral saturation, natural crystalline features, and occasional chatoyant malachite formations. Cut from two original stones and preserved as old stock, these pieces represent increasingly scarce material rarely seen in polished slab form. Each slab has been hand-cut and finished in-house to reveal the luminous green-blue body color, with select pieces featuring natural crystal pockets and malachite inclusions that add depth and geological character. The result is a collection that balances refined polish with raw mineral presence — equally suited for high-end jewelry or curated mineral display. These are stones chosen for color, rarity, and visual movement, prepared for artists and collectors who value material with provenance.
