Marine Black
Marble

Marine Black Marble is quarried across the Dharavadh-Bundi belt spanning Pratapgarh and Bundi districts in southeastern Rajasthan. While Rajasthan is best known internationally for its white and green marbles, the Bundi belt produces refined black marbles distinguished by subtle vein patterns that resemble marine forms — wave-like and flowing rather than the sharp linear veining of typical black marbles.

Gemarix sources Marine Black directly from quarry operators across the Pratapgarh-Bundi corridor, allowing us to control block selection for vein character and contrast quality. The marine vein patterning varies between blocks, and project-matched supply requires hands-on selection at the quarry stage. Our direct relationships in this less-commercialised corner of the Rajasthan stone industry make consistent supply possible for export specifications.

Marine Black is a fine-grained metamorphic marble with a recrystallised calcite matrix dominated by carbonaceous mineral concentrations responsible for its deep black colouration. The subtle marine veining is produced by clay-derived and minor calcite recrystallisation that flowed in wave-like patterns along metamorphic foliation planes during the regional orogenic events that built the Aravalli range. The flowing rather than linear pattern character is what gives Marine Black its distinctive name. Origin and specifications verified by Gemarix.

Marine Black slabs present a deep, almost ink-like black field with subtle white-grey veining flowing across the surface in wave-like marine patterns. Some blocks present near-uniform black fields with minimal veining; others carry richer flowing white movement that gives slabs sculptural graphic depth. Book-matched pairs amplify the marine effect, producing mirrored compositions that read as flowing natural artwork.

The marble pairs strikingly with contemporary design palettes — against pale oak, brushed brass, and white walls it provides dramatic visual focus; against darker palettes it adds depth and sophisticated contrast. Polished finishes maximise the black character and vein contrast, producing a high-reflectivity surface ideal for feature applications; honed finishes soften the contrast and suit floor installations.

Marine Black Marble is most commonly specified for feature walls, vanity tops, kitchen islands, fireplace surrounds, and luxury bathroom installations where the dramatic black character with marine veining is the design intent. Its visual weight makes it effective as both a primary feature material and a sculptural accent in contemporary projects.

Gangsaw slabs (280 × 180 cm) suit feature wall installations where the marine veining can flow across maximum surface area. Cutter slabs (180 × 60 cm) are typical for vanity tops and bathroom installations. Book-matched pairs are particularly effective and frequently requested — our facility in the Bundi belt selects adjacent slabs from the same block for projects where mirrored marine patterns enhance the dramatic effect.

Polished finish maximises the black character and white vein contrast — the most frequently specified finish for feature walls and vanity tops. Honed finish softens the surface and produces a contemporary matte ideal for floor applications. Leathered finish introduces gentle surface texture that complements the dramatic colour. 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 kitchen and bathroom environments. Clean with a pH-neutral stone cleaner — avoid acidic cleaners and abrasive pads, which etch calcite. Blot spills promptly, particularly wine, coffee, and oil. The black colouration is intrinsic to the stone's mineralogy and will not fade under normal interior conditions when correctly sealed.
