Nifontovite Specimen - Rey y Reina Mine Charcas Mexico
This offering (Nifontovite Specimen - Rey y Reina Mine Charcas Mexico) is a premium, matrix-free specimen of Nifontovite—a highly sought-after hydrous calcium borate from the celebrated Rey y Reina Mine (King and Queen Mine) in Charcas, San Luis Potosí, Mexico.
The Nifontovite from this specific locality is recognized globally for its superior crystallization. Note the development of white to clear, prismatic to acicular crystals that demonstrate excellent lucidity and sharp terminations. Its delicate nature and highly restricted occurrence make it a mandatory addition for advanced mineral collections, especially those focusing on rare borates or Mexican skarn-related species.
The Rey y Reina Legacy: This mine, part of the greater Charcas district (famous for its Ag-Pb-Zn-Cu skarn deposits), is the definitive type locality for high-quality Nifontovite. Specimens from Rey y Reina are the standard against which this rare mineral is judged worldwide.
