Extraction Method

Diamond wire, for clean blocks.

Our blocks are extracted exclusively with diamond wire and hydraulic splitters. Unlike blasting, this method guarantees blocks free of internal microfractures — a decisive quality factor for sawing yield and the strength of the finished slabs.

Every block is numbered right at the quarry, weighed and photographed before loading. An identification certificate accompanies every shipment.

Selection is visual and tactile: compactness, black colour homogeneity, absence of weakness planes, regularity of sawn faces. Only blocks meeting all these criteria are accepted for export.
