One of the lesser known, yet important localities for Rhodochrosite in Colorado is the Climax Mine. This mine is actually a Molybdenum mine with a very large open pit and some underground tunnels. This floater specimen hosts a single, gem quality, doubly-terminated, "needle" Quartz crystal with a few sharp, translucent, red/pink rhombohedra of Rhodochrosite perched directly in the center. Ex. Jaime Bird Collection.
