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 specimen hosts a few gem-quality, sharp, lustrous, colorless "needle" Quartz crystals with a few sharp, translucent, red/pink rhombohedra of Rhodochrosite perched directly in the center. A very aesthetic specimen from this classic Colorado locality. Ex. Richard Kosnar Collection.
