Marcasite,Fluorite & Drusy Quartz, from Zacatecas, Mexico This specimen came from an old 60's collection. The color of the gray fluorite in this specimen, is just a touch darker. The light needed for the camera lightened the specimen a little. It really looks like gray velour especially with the druzy coating. The marcasites are very sharp and mostly undamaged. This specimen displays well from any side.
