Honeycomb Calcite

Hardness: 3 on Mohs scale; Color: Honey-yellow, orange, brown; Luster: Vitreous to pearly; Crystal structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral; Specific gravity: 2.71

Formed through the deposition of calcium carbonate in caves or from hot spring mineral water. The specific 'honeycomb' structure is often a result of unique mineral precipitation patterns or the petrification of ancient coral/biological structures over millions of years, commonly dating back to the Utah sedimentary formations.

Primarily used for interior decoration, ornamental carvings, stone slabs, countertops, and by collectors for its unique aesthetic and metaphysical appeal.

Utah, USA, is the world's primary source for high-quality Honeycomb Calcite. It is unique in that it can be backlit to create a glowing effect due to its translucency. It is often referred to as 'The Gold of the Earth' by local collectors.

Identify by its distinctive 'honeycomb' or cellular surface pattern and its reaction (fizzing) to weak acids like vinegar. Collectors should look for the characteristic rhombohedral cleavage and its relative softness compared to quartz. It is most commonly found in veins or as massive deposits in arid, mountainous regions.
