Stone inlay is a decorative technique in which pieces of cut or ground stone are set into a base material so their surfaces form a continuous, flush plane. Stone inlay is also known as pietra dura in contexts describing hardstone inlay. The resulting motif can be geometric, vegetal, figural, or text-based, depending on craftsmanship.

Materials vary widely. Common stones include marble, serpentine, jasper, lapis lazuli, turquoise, malachite, onyx, and obsidian. Substrates range from architectural marble or limestone to wood, plaster, or metal supports, with the choice dictated by desired durability and contrast.

Process: a design is prepared and stones are carefully cut to fit pre-cut cavities or mortises. The stones are fitted, secured with traditional lime-based mortars or modern epoxies, and then the surface is ground and polished to align with the base.

History and contexts: Stone inlay has ancient roots in various cultures. It is a hallmark of Persian and Indian architecture, notably the Mughal pietra dura technique used to embed semi-precious stones into white marble, as seen in palatial interiors and decorative panels, including the Taj Mahal. In Europe, pietra dura and related inlay flourish appeared in Renaissance workshops and in wood inlay marquetry.

Considerations: The approach requires precise cutting and color selection to avoid gaps; durability depends on substrate and setting method; repairs can be complex, often requiring re-cutting of neighboring stones.
