Gold Crystals on Iron Oxide Matrix
Placer County, California
An exceptionally rare and extraordinary gold specimen from California, unlike anything seen before. This piece features a remarkable matrix composed of iron oxide (a form of limonite), native arsenic, and native lead—a unique mineral combination never documented elsewhere in the state.
The gold crystals themselves boast an impressive purity of approximately 95% gold and 5% silver, resulting in a warm, saturated yellow color with stunning luster. Their crystal morphology is equally remarkable, showcasing a mix of modified flat octahedral formations and richly clustered, leafy gold crystals. Visible from all angles, this specimen is an outstanding representation of its locality and a must-have for any serious collector seeking rarity and beauty in one breathtaking piece.
