Our semi-precious products

Our semi-precious products are natural quartz. They are extracted in their raw natural state. This is a natural stone characterized by the compresence of quartz and semi-precious stones. Each material is exclusive, and each slab has its own history due to the type of terrain and the minerals which compose it.

Our semi-precious are unique, due to the fact that they are not assembled in a lab and the gemstones and are not encrusted by men

It is a very compact material, which means it does not absorb the liquids it may come into contact, nor the surrounding smells. It represents the best choice for interiors, as its optical properties and its typical features lead to the creation of highly sough after environments and atmospheres.

The range of our semi-precious presents transparent, bright materials with unique and very rare colours.


All our natural quartzes are exclusive and unique, extracted from quarries of our property. For this reason, we can guarantee large blocks to obtain slabs of high aesthetic value.
