Smithsonite (566)

specimen number:
8811753

location:
Monte Cristo Mine, Rush, Arkansas, USA

description:

Beautifully chatoyant botryoidal crystallized smithsonite aesthetically arranged the top matrix. One area of damage is present along the backside of the piece as shown up close in the video. This actually gives a good idea of the underlying smithsonite and the translucency and color that is present there. Overall I think this an exceptional miniature specimen for this famous locality. This specimen was on public display at the 2026 Tucson Gem and Mineral show.

The Monte Cristo Mine near Rush in Marion County, Arkansas, was part of the rich zinc mining district of the Ozark region that was developed in the late 1800s and early 1900s. Mining focused on zinc ore, primarily sphalerite, from deposits in limestone. In the oxidized zones of the mine, smithsonite formed as a secondary zinc carbonate mineral, often occurring as botryoidal masses and smooth crusts. Smithsonite from the Rush district, including the Monte Cristo Mine, is well known for its soft colors such as blue, green, and pink, and is highly valued by collectors for its attractive appearance and classic locality.
