Honey calcite (likely rough calcite)
Calcite, CaCO₃
AI-generated identification · may be incorrectPale honey-yellow to tan, translucent edges, with a vitreous-to-waxy luster and irregular cleavage/fracture. Calcite has Mohs hardness 3, trigonal crystal structure, and specific gravity about 2.7; the image alone does not confirm the identification.

Physical properties
Pale honey-yellow to tan, translucent edges, with a vitreous-to-waxy luster and irregular cleavage/fracture. Calcite has Mohs hardness 3, trigonal crystal structure, and specific gravity about 2.7; the image alone does not confirm the identification.
Formation & geological history
Calcite forms in many settings, including limestone and hydrothermal veins, through precipitation from calcium-rich water. Its age cannot be determined from the image.
Uses & applications
Calcite is used in cement, lime, and industrial fillers; attractive translucent pieces are collected or used decoratively.
Geological facts
Calcite effervesces in dilute acid and can show double refraction in clear crystals.
Field identification & locations
A softness test and acid reaction can help distinguish calcite, but avoid damaging a display specimen. Calcite occurs worldwide, especially in limestone regions and mineral veins.
