Silky Black Marble
Silky Black is Pakistan's signature deep-black marble, quarried in KPK and Balochistan. It has a rich, uniform black base with a smooth silky polish that reflects light beautifully, and it costs PKR 85–110 per sq ft depending on grade. Architects specify it for luxury flooring borders, staircases, and high-contrast feature walls.

About Silky Black Marble
Silky Black Marble is quarried from established concessions in Pakistan's KPK and Balochistan mining zones, where dense limestone deposits formed millions of years ago under intense geological pressure. The result is a remarkably uniform deep-black stone with a fine crystalline structure that takes an exceptional mirror polish — the "silky" finish that gives this marble its name.
What sets Silky Black apart from other dark stones is its consistency. While many black marbles show heavy white veining or cloudy patches, premium-grade Silky Black holds a solid, even tone across full slabs. This makes it the go-to choice for architects who want drama without visual noise — think sleek hotel lobbies, modern villa staircases, and bold kitchen islands.
Compared to its famous cousin Black & Gold marble, Silky Black is the quieter, more versatile option — no gold veining to work around, just pure black elegance at a friendlier price point. See our full Pakistan marble price index for how it compares across varieties.

Kitchen countertop slabs typically cost 3–4× the flooring rate due to 30mm thickness and edge fabrication. Stair treads in single-piece 12"×48" format are priced per step — ask on WhatsApp for exact stair pricing. Use our stone cost calculator for a full project estimate.
Best Uses for Silky Black Marble
Flooring Borders
The number one use. A black border around Ziarat White or Tavera flooring creates the classic Pakistani luxury look.
Staircases
Single-piece treads hide scuffs and define step edges clearly. See our staircase design guide for bullnose options.
Kitchen Countertops
Dramatic black counters pair beautifully with white cabinetry. Seal annually — like all marbles, it needs protection from acids and oils.
Bathroom Accents
Vanity tops and shower feature walls. The dark tone adds spa-like depth to small bathrooms.
Feature Walls
Book-matched black slabs behind TVs or reception desks. Honest note: book-matching works best on Grade A lots with consistent tone.
Outdoor (with care)
Grade C works for shaded outdoor areas. Avoid direct harsh sun — black stone absorbs heat and can get uncomfortably hot underfoot.
Silky Black vs Black & Gold Marble
Buyers most often confuse these two Pakistani black marbles. Here is how they differ:
| Silky Black | Black & Gold | |
|---|---|---|
| Price (PKR/sq ft) | 85 – 110 | 150 – 250 |
| Appearance | Solid deep black, silky uniform tone | Black base with dramatic gold veining |
| Veining | Minimal — clean look | Bold gold veins — statement look |
| Best for | Borders, stairs, modern minimal interiors | Feature walls, luxury lobbies, countertops |
| Choose it if… | You want elegant black at a practical price | You want maximum visual drama and prestige |
Verdict: Silky Black wins on value and versatility; Black & Gold wins on wow-factor. Many clients use both — Silky Black for stairs and borders, Black & Gold for the feature wall.
