Rough Green Calcite Specimen Appraisal

Rough Green Calcite Specimen

This is a natural mineral specimen consisting of rough, unpolished Green Calcite. Physically, the item exhibits the characteristic 'waxy' or soapy luster typical of the carbonate mineral family. The color is a vibrant pistachio or lime green that transitions into pale, semi-translucent minty shades. A significant horizontal inclusion or structural band of brown/rusty host rock or iron oxide staining traverses the middle of the specimen, creating a distinct visual break in the green crystal structure. The specimen appears to have a rhombohedral cleavage, visible in the jagged, stepped edges where the crystal has naturally broken away from a larger vein. In terms of condition, the specimen is in a raw, natural state with visible internal fractures and surface abrasions, which are common for this soft mineral (rated 3 on the Mohs hardness scale). There are no secondary treatments like polishing or acid-washing visible, preserving the natural texture. The translucency is moderate, allowing light to penetrate the upper green portion. No maker's marks or signatures are present as it is a geological sample. Specimens of this quality and color are frequently sourced from Mexico and are popular in metaphysical and geological collections due to their soothing color palette and accessible price point.
