納瓦洪
La Rioja, Spain
西班牙拉里奧哈的納瓦洪以一樣東西聞名於世:完美的天然黃鐵礦立方體。
What it is known for
The Ampliación a Victoria mine at Navajún produces strikingly sharp, bright pyrite cubes — single crystals and groups — weathered free from a grey marl matrix.
What collectors look for
Mirror-faced, undamaged pyrite cubes (loose or on matrix) are the prize; sharpness and lustre drive value.
