The Cameo Artistry

Every cameo created by ALEXANDRA is a testament to meticulous craftsmanship and careful material assortment. The process begins with the selection of premium sections of sardonic shell (Cassis Madagascariensis), sourced from the Caribbean Sea. These shells are notable for their two naturally contrasting layers of colour that provide a natural palette for the engraver's artistry. The upper, white layer of the shell is expertly carved by hand, creating intricate micro-sculptures that bring each design to life against a rich, dark beige background referred to as the "monk colour". In addition to this classic approach which offers designs engraved in relief, ALEXANDRA sets itself apart through innovative experimentation with "negative" engraving. In this process, aesthetic motifs are carefully incised into the predominant white surface of the sardonic shell, producing striking dark lines that interact with the natural colouration of the shell.

 

 

Shell splitting is the stage in which the whole shell is prepared in order to obtain the section suitable for cameo carving. After identifying the most appropriate area, the artisan uses specialized tools to separate the outer shell cap from the rest of the shell, following its natural structure and taking great care to avoid unwanted cracks or fractures. This process requires considerable experience and precision, as the shell is simultaneously strong yet delicate when subjected to excessive stress. The quality of this initial phase is decisive for the success of the cameo, as a natural and irregular surface now takes on a more uniform appearance. The purpose of shell splitting is to obtain an intact section with the appropriate thickness and color characteristics suited for the subsequent artistic work.

 

 

Marking is the initial phase of cameo crafting. The artisan carefully observes the shell and roughly traces the design to be created on its surface, taking into account the shell's natural conformation — its curves, recesses, and reliefs — as well as the different shades of its layers. This operation is essential to best enhance the subject, selecting the portion to be used for the varied inspirations of the final jewel.
After marking, the shell is cut using a smaller cutting disc than the one used for splitting ("cutting"), in order to obtain the portion best suited for the creation of the cameo. The cut must be precise and accurate, so as to respect the dimensions of the jewel and preserve the integrity of the material.
The shaping process ("garbatura") is refined by using a fine-grained emery wheel. The artisan thus removes superfluous parts and gives the piece its desired form, modelling the edges to obtain the "shaped" cameo ready for the subsequent engraving phases.

 

 

Engraving represents the heart of the cameo jewel-making, for it is in this process that the material comes to life and takes shape. It begins with rough carving, a phase in which the outermost layer — the conchiolin — is thinned to remove excess material. At this point, the subject to be depicted is drawn with precision onto the surface. The "burins", the tools used for engraving, feature different sized tips and cutting edges. The broader ones are used for the preliminary sketch, with the first intermediate forms beginning to take shape, then becoming flat planes — the wider surfaces of the relief — progressing to the pianettine, the intermediate surfaces that define volumes and levels. The modelling then refines every detail, creating nuances, highlights and shadows. Using the "ugnarella" — an extremely fine metal tool — the transitions between planes are smoothed and the most minute and delicate details are finished. Finally, the cameo is detached from the pitch and treated with oil, which enhances the nuances, then washed to remove any residue. These steps not only preserve the cameo overtime but also enhance the contrasts and elegance of the relief, giving the jewel a timeless luster.
