Physical properties
Hardness of 3 on the Mohs scale, with a vitreous to dull luster. It displays banded colors ranging from white and cream to reddish brown and grey, featuring a microcrystalline to fibrous crystal structure.
Formation & geological history
Formed through the precipitation of calcium carbonate from mineral-rich waters in caves or hot springs. Geological age varies widely depending on the specific deposit.
Uses & applications
Used widely as a decorative stone, polished slab specimens for collectors, and historically as architectural building material.
Geological facts
This specific cut specimen reveals the intricate internal concentric ring growth patterns of a stalactite cross-section. Travertine is a terrestrial sedimentary rock formed in mineral springs.
Field identification & locations
Easily identified by its characteristic concentric banding, porous texture, and reaction to hydrochloric acid. Commonly found in limestone caves worldwide.
