Travertine – Diagenesis and petrography  

Considered since ancient times a decorative product with excellent technical and aesthetic qualities, it was among the most valuable Roman travertines used in the construction of public and private buildings of the Roman and modern times. The Travertine from this deposit is one of a kind. The reef has a limited areal extension and limited thickness, being typical and exclusive of the area between the Treia River and Monte Soratte. The cultivation of this peculiar field has been limited, in the past, by impediments related to the extraction techniques. Today, using the most modern extraction techniques, Kingstone brings to light what can be defined as the maximum expression of white Roman travertine. The growth of the travertine bench continued with limited dragging, therefore it is a predominantly stromatolytic indigenous deposit. Stromatolytic travertines (with encrusting algae) consist of a succession of single sheets, often with an alternation of light and dark millimeter sheets. The laminae can be subparallel to wavy. Sometimes they are separated by more or less regular surfaces of discontinuity. Generally they are related to laminar water flows, and are formed in shallow basins characterized by the rapid flow of water (overflow basins). The facies described above can be associated with that of well cemented porous travertines, with incrustations in the life position. The porosity is due to the presence of voids corresponding to the internal casts of the plant structures on which the travertine has grown, subsequently decomposed. The genesis of the travertines of central Italy is part of a very complex and volcanically active geological context, with areas in the relaxation phase accompanied by a series of volcanic phenomena not necessarily in an effusive condition and not necessarily quiescent, whose interaction with infiltration waters that come from the surface allows processes of mineralization, interaction with the carbonate sediments present and then of final genesis of the thermal travertines. The travertines cultivated by Kingstone srl fit well into the geological and sedimentological framework outlined above, they have an endogenous origin due to the leakage of supersaturated calcium carbonate fluids in correspondence with faults related to the geological evolution of central Italy, therefore of the Apennines and graben of the Tiber River which led to the tectonic isolation of Monte Soratte and the evolution of the Sabatino Volcano. The travertine cultivated by Kingstone is compact, hard, without gypsum, with very regular veins and low porosity. Therefore, a stone that stands out not only for its purely decorative dimension but also offers excellent technical performance, as a peculiar characteristic among white Travertines.

KingStone travertine 

KingStone Travertine is a white travertine with ivory or gray veins, sometimes regular and sometimes wavy. The “pitched” cut, ie following the direction of the lay, gives a cloudy appearance. The cut “against the flap”, orthogonal to the direction of lay, highlights the characteristic veins. The high hardness and compactness guarantee excellent polishability. It is a very popular material due to its great versatility. It comes in three main shades, with light and thin veins, with more evident Ivory / Gray veins and with thicker hazelnut-colored veins.
