Rhodochrosite / Sphalerite / Locality - Eagle Mine, Gilman, Eagle County, Colorado


Shipping to United States: Free

Several vibrant pink colored “rosettes” comprising compressed rhombohedra or “discs” of Rhodochrosite are intergrown and gently sprinkled atop beautifully contrasting black Sphalerite matrix to make this small cabinet display specimen a top notch representation of the material from this famous locality. The Rhodochrosites from this mine are not the typical blocky rhombic habit like those seen from a lot of other ore bodies in Colorado, and this particular pocket that produced the fiery pink crystals on the stark black Sphalerite are some of the my favorite Rhodochrosite specimens from Colorado. For reference, there is underlying Pyrite below the Sphalerite, but it cannot be seen from the display side. A beautiful piece from the world famous Eagle Mine (more properly the New Jersey Zinc Eagle Mine). This mine is long defunct and will never produce these specimens again. They are highly prized among Colorado collectors for their unique form and obvious beauty. You can’t get these pieces anymore, they’re not just available, and only a few truly fine specimens of this material exist. The Rhodochrosite from this mine ranges in its chemistry from the far manganese end to an iron / manganese mix, all the way to tan / brown Siderite at the other end of the series. Good crystallized Rhodochrosites from this locality are among the most distinctive from Colorado, and highly sought after by collectors. The Eagle Mine was the center of lead and zinc mining in Colorado for a time, and produced some of the state’s most memorable mineral specimens, along with the neighboring Groundhog Mine that produced the finest Wire Gold specimens in the world extant!
