All the Lunigiana stele statues are made of sandstone: it is a compact stone attributable to the formation of the boulder, a sedimentary rock from the upper Oligocene. This type of sandstone is very common in the Magra River valley in the form of stratified blocks, more or less rounded due to the transport carried out by the impetuous torrents descending from the mountains. The carefully selected sandstone block, before being carved, was shaped into a geometric form through extensive processing, almost always on all surfaces.

Once the shape was obtained, the image was completed with bas-relief, which involved lowering the background of the surface while leaving the areas that were meant to represent anatomical details (arms, hands, breasts) and attributes (weapons, jewelry) untouched.

To achieve this, the figurative parts were first outlined with a sequence of percussion marks and then connected with grooving. Once the engraved design was completed, the relief was created by lowering the background. Stone tools were likely used for the creation of these statues. A percussive tool was used to shape the general form of the stele and to emphasize the anatomical parts and accompanying objects. A small flint blade, used like a saw, was used to refine the contours of the figurative parts and highlight certain details like the fingers of the hands.

With a drill, consisting of a flint tip mounted at the end of a stick and rotated between the hands, the eye holes were made. Silica sand or a harder sandstone pebble was used as an abrasive to smooth the surfaces worked with hammering. Finally, the inscriptions found on later groups of stele statues were engraved using steel-tipped tools.
