Agate Quartz Geode Pair – Brazil

This matching pair of agate quartz geodes from Brazil measures 27 × 15 cm combined and weighs 9.6 kg. Cut and polished as a set, each half reveals the same layered agate banding around a crystalline quartz interior — agate's characteristic bands form as silica-rich fluids deposit in successive layers inside a rock cavity, with the two halves of a single geode naturally mirroring each other once split. At this scale and weight, the pair works equally well as a striking pair of bookends or as a stand-alone decorative statement.
