KingStone has been operating in the field of extraction, processing and sale of natural stones for four generations,
a culture since 1870 handed down by tradition of expert stonemasons and quarrymen.

Over the years, the family has been involved in the cultivation and recovery of various marble and travertine quarries, in Italy and abroad.
A first pink marble quarry was cultivated by the family in the 1950s on the slopes of Mount Soratte.

Kingtone has always considered fundamental, in carrying out its production and extraction activities, the needs of respect for the environment and in particular that of landscape protection aimed at restoring and preserving the quality of the territory.

The company adopts the innovative cultivation system “by sectors”, whereby the recovery of the area takes place at the same time as the extraction works. The quarry area of the cultivated sector is returned to its agricultural purpose already during the cultivation of the next sector.

Before the start of cultivation, the soils are subjected to geochemical analyzes in order to identify the “0” point not to be altered. Furthermore, in compliance with international environmental protection standards, all the guidelines of the UNI EN ISO 14001: 2015 standard are adopted.
