AI-assisted summary

Description from the seller

An example of extreme mineralogical rarity. The Dolomite (CaMg(CO₃)₂) with intense blue coloration is a highly unusual variety in nature, with discoveries in Colombia being the most important and well-documented source internationally.

The piece is a polycrystalline aggregate characterized by a modified rhombohedral habit. The crystals exhibit a distorted morphology with perceptible curvatures on faces and edges, a crystallographic feature indicating unique growth conditions (often associated with the incorporation of trace elements).

The tone is of a deep, saturated blue. This color, combined with its atypical morphology and exclusive origin, makes it a highly valuable specimen both systematically and aesthetically, making it a crucial addition to any collection specializing in carbonates.
