Random Natural Stone Mosaic
Irregular stone pieces hand-set on mesh with an unrepeating joint pattern — the most organic of the mosaic formats and the one that hides substrate movement best.

A soft, warm-toned sedimentary stone carved and cut in Central Java. Specified for interiors, shaded exteriors and carved relief work where the design calls for warmth rather than the coolness of volcanic grey.
Indonesian limestone — known locally as batu paras — is a fine, workable sedimentary stone in the cream and ivory range. It is softer than the volcanic stones and that softness is exactly why it is chosen: it carves. Much of the relief panelling, screen work and ornamental detail in Balinese and Javanese resort architecture is limestone.
For flat work it produces a calm, warm surface with far less tonal noise than most imported travertines. In shaded exteriors, courtyards and covered terraces it holds up well; in fully exposed wet climates it weathers and develops patina faster than andesite, which some architects specify for deliberately.
We supply limestone as tile, cladding, cut-to-size panels, carved relief and custom ornamental work produced from your drawings.

Stone bars aligned in a true stack bond with continuous vertical and horizontal joints — the most disciplined mosaic pattern, for precise contemporary work.

Precision-cut stone hexagons on mesh — the most specified geometric mosaic for bathrooms, kitchens and contemporary interior floors.
View Product
Rectangular stone bars set at 90° in a classic herringbone, mesh-mounted so the pattern lands accurately without site setting-out.
View Product
Paired stone bars alternating in direction around a contrast dot — a traditional pattern that reads as texture rather than geometry from a distance.

Large irregular flagstones with fitted joints, supplied loose by the square metre or mesh-mounted for faster installation.

Panels cut with an interlocking profile so adjacent modules key into each other and the panel joint becomes invisible.

Yes. Send a dimensioned drawing or reference photograph and we will quote per panel with a sample carving for approval before the full production run.
In wet tropical exposure limestone develops patina and can host algae on permanently shaded damp surfaces. Sealing slows this considerably. In dry climates such as the Gulf it stays close to its original tone.
