River Blue
Marble

River Blue Marble is quarried in Rajsamand district, central Rajasthan, within the Aravalli marble belt. River Blue takes its name from the flowing water-like patterning visible across slab surfaces — directional movement that suggests river currents or flowing water rather than geometric veining. This distinctive patterning combined with the cool blue-grey palette has made it a sought-after specification for contemporary projects.

Gemarix sources River Blue directly from operators in the Rajsamand belt, allowing block-by-block selection for the flowing patterning that defines the material. The river-like patterning varies significantly between blocks — some present restrained character, others carry richer, more dramatic flowing patterns. Our direct relationships allow project-matched supply for export specifications where the patterning is integral to design intent.

River Blue is a fine-grained metamorphic marble with a recrystallised calcite matrix and characteristic cool blue-grey colouration. The blue tones come from minor concentrations of riebeckite and amphibole-group minerals; the flowing river-like patterning comes from clay-derived and carbonaceous material that was stretched and folded along strong metamorphic foliation planes during the orogenic events that built the Aravalli range. Origin and specifications verified by Gemarix.

River Blue slabs present a cool blue-grey field with flowing directional patterns that read as water movement across the surface. The patterning is sculptural and atmospheric — not the sharp linear veining of typical marbles, but flowing curves and gradient transitions that suggest natural water character. Book-matched pairs are particularly effective for amplifying the river-like effect.

The marble pairs strikingly with contemporary design palettes — against brushed steel, blackened metal, and pale oak it provides cool sculptural depth; against warmer palettes it adds tension and visual interest. Polished finishes maximise the blue character and pattern depth; honed finishes pull the surface towards a contemplative matte that emphasises atmospheric quality over reflectivity.

River Blue Marble is most commonly specified for contemporary residential bathrooms, feature walls, vanity tops, hotel spa installations, and luxury kitchen applications where the cool blue character and flowing patterning are the design intent. Book-matched installations are particularly effective for vanity walls and shower surrounds.

Gangsaw slabs (280 × 180 cm) suit large feature cladding installations where the river patterning can extend without joints. Cutter slabs (180 × 60 cm) are typical for vanity tops and bathroom installations. Book-matched pairs are highly effective and frequently requested — our Rajasthan facility selects adjacent slabs from the same block for projects where mirrored river patterns enhance the design.

Polished finish maximises the blue character and pattern depth — most often specified for feature walls and vanity tops. Honed finish softens the surface and produces a contemplative matte ideal for floor applications. Leathered finish introduces gentle surface texture that complements the flowing patterning. Brushed finish is occasionally specified for industrial-contemporary applications.

This stone is supplied in two production formats. Gangsaw slabs are large-format slabs for premium architectural projects requiring continuous surfaces. Cutter slabs are smaller-format slabs optimised for residential installations and tile production.

Gangsaw Slabs

260–300 cm × 160–180 cm × 2 / 3 cm

Cutter Slabs

180–220 cm × 60–90 cm × 2 / 3 cm

Custom tile sizes available: 60×60 cm, 60×90 cm, 90×90 cm. Cut to specification at our Rajasthan facility.

Apply a penetrating stone sealer at installation; reseal annually in bathroom and kitchen environments. Clean with a pH-neutral stone cleaner — avoid acidic cleaners and abrasive pads. Blot spills promptly. The blue character and flowing patterning are intrinsic to the stone's mineralogy and remain stable under normal interior conditions when correctly sealed.
