Riquiqui Montaigne no. 4 is a sculptural vase carved from a raw stone fragment, preserved as much as possible in its original form. The block is worked with minimal intervention, leaving fractures, irregular edges, and natural colour variations visible.

The surface shows shades of brown and grey, with a compact, dense appearance. The finish is matte, keeping the material open and tactile, and preserving the stone’s raw character.
