Xingyan Stone Polishing Sparkling Gray Marble Stair Manufacturer

Quarried from premium deposits, this marble features a base of soft gray veining interspersed with tiny quartz crystals that catch light, creating a “sparkling” effect.

Natural variations in veining ensure each stair is unique, adding warmth and character to any space.

Multi-stage polishing (up to 3000 grit) achieves a high-gloss finish that enhances the stone’s natural luster and depth.

Optional honed or leathered finishes for a more understated, matte look.
