Diamond polishing isn't one step — it's a progressive refinement through multiple grit stages. Here's our proven process.
We evaluate your marble's type, condition, and existing finish. Carrara requires different grit sequences than Calacatta or Emperador. We identify what's needed before any work begins.
We thoroughly clean the surface and protect surrounding areas. Furniture is shifted, and surrounding surfaces are masked off. Diamond polishing is a wet process — completely dust-free.
Starting with coarse grit to remove damage and level the surface, then progressing through medium and fine grits. Each stage refines the surface further, eliminating the scratches from the previous stage.
The finest diamond abrasives and polishing compounds create the mirror finish. For extra durability, we can apply a crystallization treatment that chemically hardens the surface while enhancing gloss.
A penetrating impregnating sealer is applied to protect the freshly polished surface. This creates an invisible barrier against oil and water-based stains while allowing the stone to breathe. Your marble stays polished and protected longer.
The Difference
Unpolished marble doesn't just look bad — it's absorbing stains, trapping bacteria, and degrading daily. Here's what professional diamond polishing actually changes.
A polished marble floor bounces natural light deep into your space. Manhattan apartments feel larger, lobbies feel grander, and rooms that once felt dim suddenly glow. It's not just cleaning — it's optical architecture.
Dull marble has open, microscopic pores — absorbing red wine, coffee, cooking oil. Polishing closes those pores at the surface level. Sealing fills them deeper. Together, they create a barrier that stops stains before they start.
In Manhattan, marble isn't just a surface — it's an asset. A dull, etched floor signals neglect. A mirror-finish floor signals that the property has been maintained at the highest level. Buyers and tenants notice the difference instantly.

Common Questions
Marble floors in Manhattan homes typically need professional polishing every 3-5 years depending on traffic. Kitchen countertops may need polishing every 2-4 years due to daily use. Bathroom marble lasts longer — 5-7 years between polishing. High-traffic commercial lobbies may need annual maintenance. Call (212) 401-4036 to assess your marble's current condition.
We use industrial diamond abrasives — not polishing powders. Diamond pads are more aggressive, more consistent, and produce a superior finish. Powder polishing is a shortcut some companies use; it masks problems rather than correcting the surface. Our diamond process physically refines the stone at a microscopic level for results that last years, not weeks. Call (212) 401-4036.
None. Diamond polishing is a wet process — water cools the diamond pads and captures any particles at the source. There is zero airborne dust. For floor polishing, we mask off adjacent areas to contain water spray. Your home stays clean — we've worked in furnished Manhattan apartments for 25+ years without a single complaint. Call (212) 401-4036.
Yes. We can achieve any finish level — from a high-gloss mirror polish to a soft satin hone. If you're polishing one area (like a kitchen island) and want it to match adjacent marble (like flooring), we'll match the sheen precisely. We can also change your finish — converting a polished surface to honed, or vice versa. Call (212) 401-4036 to discuss your preferences.
All types: Carrara, Calacatta, Statuario, Emperador, Crema Marfil, Nero Marquina, and specialty marbles. We also polish travertine, limestone, terrazzo, onyx, and granite. Each stone gets a customized grit sequence based on its hardness and mineral composition. Call (212) 401-4036.

Yes — to an extent. Surface-level stains, water rings, and etching are removed during diamond polishing as the top micro-layer of marble is refined away. Deep-set stains (like red wine or oil that has penetrated deep into the stone) may require a poultice treatment before polishing. During our free assessment, we identify which stains will lift with polishing alone and which need additional treatment. Call (212) 401-4036 for an evaluation.

A properly polished marble floor is smooth and reflective but not dangerously slippery — especially when dry. For added safety in bathrooms, entryways, or homes with children and pets, we recommend a honed (matte satin) finish which provides more natural grip while still looking beautiful.
