- Colors: Red, orange, brown, and even colorless (clear crystals).
- Forms: Crystals range from small, sharp, and well-formed to larger, blocky masses.
- Notable Features: Some of the best sphalerite specimens from Elmwood exhibit a striking translucent quality with an almost glass-like luster.
2. Fluorite
- Description: Elmwood Mine is also well-known for its fluorite specimens, which range in color from pale greens to vibrant purples. Fluorite is often found as cubic crystals and can exhibit interesting fluorescence under UV light.
- Colors: Green, purple, yellow, blue.
- Forms: Mostly cubic crystals, though some specimens are more octahedral.
- Notable Features: Elmwood fluorite often forms striking clusters, and the color zoning in these crystals is highly prized by collectors.
3. Calcite
- Description: Calcite is another common mineral found at the Elmwood Mine, often in association with other sulfide minerals. The crystals are typically transparent to translucent and can form in a variety of shapes.
- Colors: Colorless, white, yellow, or orange.
- Forms: Scalenohedral, rhombohedral, and even delicate twinned crystals.
- Notable Features: Many calcite specimens from the Elmwood Mine are prized for their excellent crystallization, and their distinct formations make them highly collectible.
4. Barite
- Description: Barite, a barium sulfate mineral, is found in association with many of the sulfide deposits at the Elmwood Mine. The crystals can range from clear and transparent to opaque and white.
- Colors: White, colorless, pale yellow, and occasionally light blue.
- Forms: Commonly found in tabular or blocky crystals.
- Notable Features: Barite from Elmwood is often associated with sphalerite and calcite, and collectors favor the sharpness and clarity of the crystals.
5. Galena
- Description: Galena, a lead sulfide mineral, is often found in the Elmwood Mine’s deeper levels. Though not as abundant as some of the other minerals, it is highly valued due to its metallic luster and well-formed cubic crystals.
- Colors: Metallic gray to lead gray.
- Forms: Mostly cubic, though it can also form octahedral or dodecahedral crystals.
- Notable Features: Galena specimens from Elmwood often occur as part of a mineral matrix with sphalerite, calcite, or fluorite.
6. Pyrite
- Description: Known as “fool's gold,” pyrite is an iron sulfide mineral found in abundance in the Elmwood Mine. While not as rare as some of the other minerals, its brilliant metallic luster makes it a popular specimen among collectors.
- Colors: Brass-yellow, with a metallic shine.
- Forms: Typically cubic or pyritohedral crystals, but can also form as masses.
- Notable Features: Pyrite crystals from the Elmwood Mine are often well-formed and can sometimes form in association with sphalerite or fluorite, giving them an attractive contrast.
7. Chalcocite
- Description: Chalcocite, a copper sulfide mineral, is less common but can still be found at the Elmwood Mine. It forms as dark, metallic crystals or masses.
- Colors: Dark gray to black, with a metallic shine.
- Forms: Crystals tend to be massive or in granular aggregates.
- Notable Features: Chalcocite specimens from Elmwood are prized for their high copper content and striking metallic appearance.
