Description
A raw geological specimen featuring bright, crystalline native gold veins disseminated through a quartz and iron-stained matrix. The gold exhibits a classic hackly fracture and metallic luster characteristic of high-purity lode deposits. This specimen represents the primary source of gold before industrial refining, showcasing the metal in its original host rock environment.
