Toros Black Marble: Quarry, Look, Finishes and Project Uses
Black marble makes a strong statement, so small differences in color, veining and finish matter. Toros Black, known in Turkish as Toros Siyahı, is a black marble with fine white calcite veins. It takes its name from the Taurus (Toros) Mountains of southern Turkey.
We operate the Toros Black quarry ourselves, so this guide draws on our own published information as well as general guidance for buying black marble. It is written to help you decide whether the stone suits your project and what to confirm before you order.
What Toros Black looks like
The stone has a black ground, usually crossed by thin white calcite veins. As with any natural stone, the tone and the amount of veining can vary. Some slabs may look calm, while others show more movement. For this reason, it is best to review real slabs or bundles when appearance matters.
A polished surface generally makes the black look deeper and the veins sharper. Textured finishes can change that contrast, so the same stone can feel formal in one project and more natural in another.
Where it comes from
Our Toros Black quarry is in Saraycık village, in the Develi district of Kayseri, Turkey. The quarry was first licensed in the early 1980s, and we took over its license in 2012. Because we are the quarry owner, we work with the stone from the block stage onward, whether it is supplied as blocks, slabs or project-sized pieces.
You may see other sellers use similar names for black Turkish marbles. Names in the stone trade are not tightly regulated, so if the source matters to you, always ask which quarry the material comes from.
Published test values
The figures below come from the analysis results published on our Develi Mermer Toros Black page:
- Hardness: 3.5 to 4 Mohs
- Bulk density: 2.699 ± 0.007 g/cm³
- Water absorption by weight at atmospheric pressure (TS 699): 0.138 ± 0.043%
- Compressive strength (ASTM C170): 1448 ± 155 kg/cm²
- Flexural strength under concentrated load (TS EN 12372): 179.32 ± 19.99 kg/cm²
- Abrasion resistance, Böhme method (TS EN 14157): 15.72 ± 0.33 cm³/50 cm²
These values describe tested samples, and natural stone varies. If your project needs technical approval, ask for the relevant report and have your consultant check it against the requirements for your application. Test results for one finish or sample do not automatically apply to every piece.
What the numbers mean in practice
Low water absorption means the tested stone takes up relatively little water, but it does not make the stone stain-proof or weatherproof in every situation. A hardness of 3.5 to 4 Mohs also shows that this is a marble rather than a much harder stone such as many granites, so it can scratch and wear with use. As a calcium-based stone, it can also react with acids.
On dark polished marble, marks from acid or abrasion can be especially easy to see. A dull mark on a shiny black surface will stand out more than the same mark on a pale honed stone. Plan the finish and maintenance with that in mind.
Finish options
Toros Black can be produced in a range of surfaces according to project needs. These include:
- Polished: a glossy, reflective surface with a deep black look and clear veins.
- Sandblasted: a textured, matte surface with a very different character.
- Deep brushed or leather: a tactile surface that shows less reflection than polish.
Polish is often the first choice for walls and feature pieces, but it can be slippery when wet and shows marks easily. Textured surfaces can feel more relaxed and may hide some daily marks, though they can hold dirt differently. Our guide to choosing a stone finish explains these trade-offs in more detail.
Where it is commonly used
Toros Black is used in luxury housing, hotels and residences, and in villa interiors and exteriors. Typical applications include:
- Feature walls and fireplace surrounds
- Floors and stairs, with the finish and maintenance chosen for the location
- Vanity tops and special decorative pieces
- Contrast details alongside lighter stones
For outdoor use, stairs and wet areas, check slip resistance and durability for the exact finish and climate. Exterior applications need specific review, because sun, water and frost can affect how a stone performs over time.
What to check before you order
- Veining: how much white veining do you want, and is it consistent across the area?
- Tone: view the slabs in good light, and remember that photos can change how black appears.
- Finish: ask to see the exact finish you are specifying.
- Surface condition: check any fissures or repairs. Our guide to marble slab defects and repairs shows what to look for.
- Quantity: order for the full area at once where matching matters. See how to calculate marble quantity.
- Supply form: decide whether you need blocks, slabs or cut-to-size pieces.
Care tips
- Use a pH-neutral cleaner suited to natural stone.
- Wipe up acidic spills such as lemon juice and vinegar promptly.
- Ask your installer about a sealer suited to the finish and location.
- Use mats at building entrances to reduce abrasive grit.
- Agree on a maintenance plan with commercial clients before handover.
Frequently asked questions
Is Toros Black a good choice for floors?
It can be, but the answer depends on traffic, finish and maintenance. A polished black floor may show dust, scratches and acid marks, so discuss the location with your installer.
Can I order blocks as well as slabs?
Toros Black can be supplied as blocks, slabs and special sizes. Contact us with your requirements to discuss current availability.
Does every slab have the same veining?
No. It is a natural stone and each slab is different, so review the real material before you approve it.
