Opal White
Marble

Opal White Marble is quarried in Rajsamand district, central Rajasthan, within the Aravalli marble belt. Opal White takes its name from the soft luminous quality the polished surface reads — a subtle depth that suggests opalescent character without the actual play-of-colour of true opal. This distinctive quality has made it a sought-after specification for premium residential and hospitality projects across global markets.

Gemarix sources Opal White directly from quarry operators in the Rajsamand belt, allowing us to select for the luminous character that defines the material. Block-by-block variation in this character requires hands-on quarry-stage selection for consistent project supply. Our direct relationships make this curation possible for export buyers specifying the stone for projects where the luminous quality is integral to the design intent.

Opal White is a fine-grained metamorphic marble with a recrystallised calcite matrix and exceptionally low accessory mineral content. The luminous quality that distinguishes Opal White comes from a particular crystalline structure that scatters light through subsurface reflection rather than purely surface reflection — a marble equivalent to the optical phenomenon that gives certain whites their depth. Origin and specifications verified by Gemarix.

Opal White slabs present a soft luminous white with restrained veining and subtle depth. The polished surface reads with a quality that distinguishes it from flatter whites — light scatters through the surface rather than reflecting purely off it. Some blocks lean cooler and brighter; others present softer, warmer luminous character; book-matched pairs produce particularly effective compositions for vertical applications.

The marble pairs strikingly with both contemporary minimalist and traditional design palettes. Against pale oak, brushed brass, and matte joinery it adds quiet luminous depth; against darker palettes the depth becomes more pronounced and adds dimensional interest. Polished finishes maximise the luminous quality; honed finishes soften it to a matte that retains the depth without the high reflectivity.

Opal White Marble is most commonly specified for luxury residential bathrooms, hotel suite finishes, feature walls, and book-matched vanity installations where the luminous character becomes integral to the design. The depth quality makes it particularly effective for vertical applications where light interacts with the surface across the day.

Gangsaw slabs (280 × 180 cm) allow the luminous character to extend across full-height installations; cutter slabs (180 × 60 cm) are typical for vanity tops and feature applications. Book-matched pairs are particularly effective — our Rajasthan facility selects and cuts adjacent slabs from the same block for projects where the luminous depth is enhanced by mirrored composition.

Polished finish maximises the luminous quality and produces a depth most often specified for feature walls and vanity installations. Honed finish softens the surface to a matte that retains depth without high reflectivity, suiting bathroom floors and contemporary residential applications. Leathered finish introduces gentle surface texture and is occasionally specified for projects where the luminous quality should be present but understated. Brushed finish is rarely used for this material.

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 and soft cloth — avoid acidic cleaners and abrasive pads, which etch calcite and reduce the luminous quality of polished surfaces. Blot spills promptly, particularly wine, coffee, oil, and citrus. The luminous character is intrinsic to the stone's mineralogy and remains stable when correctly sealed.
