Description
This striking specimen features richly textured goethite in sculptural, lustrous and somewhat stalactitic formations, accented by sharp, gemmy calcite crystals along the matrix. The goethite displays deep brown to umber tones with a velvety, almost earthen surface, while the calcite introduces lighter, crystalline geometry that adds glamour and visual balance to the piece.
The overall composition feels architectural and intentional—an excellent example of how secondary iron oxides and carbonates can co-crystallize to create dramatic, naturally layered forms. A grounded, tactile specimen that rewards close inspection from every angle.
Dimensions & Weight
2.25” x 2” x 1.75”
170 g
Collector’s Notes
Mexican goethite is especially prized for its aesthetic diversity, ranging from lustrous stalactites to matte, velvet-textured growths like those seen here. The presence of calcite enhances collectability, providing both mineral contrast and insight into the geochemical environment in which the specimen formed. This piece strikes a rare balance between rugged iron oxide textures and clean crystalline structure.
Highlights
Sculptural botryoidal and stalactitic goethite
Contrasting calcite crystal growth on matrix
Excellent texture and dimensionality
Visually strong from multiple display angles
Classic iron oxide–carbonate association from Mexico
Mineralogy
Goethite is an iron oxyhydroxide mineral that commonly forms as a secondary mineral in oxidizing environments, often replacing earlier iron-bearing minerals. Its diverse crystal habits—botryoidal, stalactitic, and massive—make it a favorite among mineral collectors. Calcite, a calcium carbonate, frequently forms alongside goethite in hydrothermal and sedimentary environments, recording changes in temperature, fluid chemistry, and mineral saturation over time.
Metaphysical Properties
Goethite is often associated with grounding, emotional stability, and connection to the earth’s deeper energies. Calcite is traditionally linked to clarity, amplification, and balance, making this combination appealing to those who appreciate both the physical and energetic harmony of mineral pairings.
