Seagrass is a Turkish natural stone in green-brown, fossil-marked tones and is usually listed in the trade as a marble. At ROSSITTIS we stock it as a raw slab and for tiles and floors wherever a warm greenish limestone look with decorative depth is sought.

About Seagrass
Seagrass is a stone with a strong reference to nature. The surface works with green, brown, olive, fossil inclusions and in part cloudy movements. This makes the material appear organic and considerably livelier than a calm beige limestone. In bathrooms, wall surfaces, stairs and selected floors, Seagrass can be very convincing for precisely that reason. Compared with green marbles the image is earthier; compared with slate or gneiss it is softer and more strongly marked by fossils.
The stone originates from Turkey, from the province of Karabük in the Safranbolu-Eflani area. Geologically it belongs to the range of fossil-bearing limestones, or calcareous marbles. In the trade Seagrass is frequently listed as a marble, because surface, market position and interior use are read in exactly that direction. For planners this is a typical case in which trade language and petrographic language diverge, while the care properties clearly remain those of a calcareous stone.
Technically, Seagrass lies in a dense but acid-sensitive range. The bulk density lies, depending on the data set, at roughly between 2,656 and 2,699 kg/m³, the compressive strength between 132.06 and 145.34 MPa and the flexural strength in a load-bearing range. The water absorption lies at around 0.35 %. That speaks for a stone that can be used well indoors and in selected external situations, as long as its calcareous binding is honestly taken into account. For kitchens the material only makes sense where there is a willingness to maintain it.
In stock, antique and river-type finishes are particularly relevant. Antique underlines the warm, natural fossil effect. The surface finishes available from stock are listed in the »Finishes« block further down. At ROSSITTIS, Seagrass is available as a raw slab and for tiles and floors.
The honest assessment: Seagrass is not an easy-care kitchen substitute for granite. Its strength lies in colour, fossil structure and an unusual green-brown limestone look. Anyone looking for precisely that receives a stone of great character.

Guide values for the stone type, taken from manufacturer and test reports. Natural stone is a natural product — individual batches and slabs can differ. For critical applications, request slab-specific test data.
Seagrass is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Anticato, untreated
The Eco Antik surface is flamed and intensively brushed — this creates a more rustic, livelier look with a pronounced feel. Recommended for slip-safe interior wall and floor claddings in which the material is meant to work as a characterful statement stone with a craftsmanlike, Mediterranean appearance.
River finish
The surface is roughened by water pressure — the colour tone comes through more strongly than with flamed plus brushed. A level, slip-resistant texture with pronounced colour depth. Recommended for outdoor areas, terraces and façade surfaces where a characterful, non-slip surface with clear material depth is required.
Care & fabrication
Seagrass should be carefully impregnated on floors, stairs and working surfaces, because the stone is calcareous and thus acid-sensitive. The impregnation helps to make it harder for water, oil and coloured media to penetrate the surface.
For cleaning and care, only pH-neutral natural stone cleaners, water and soft cloths or mops are suitable. On kitchen and bathroom surfaces, limescale, soap, coffee, wine and lemon juice should not be allowed to dry on.
Avoid vinegar-based cleaners, descalers, chlorine-based household agents and abrasive pads. Seagrass can only be cleaned and cared for well over the long term if the surface is treated gently.
For interior and exterior applications, clean and care for it regularly and refresh the impregnation at sensible intervals. That keeps the green-brown surface calmer and more even.
Frequently asked questions
Is Seagrass suitable for the kitchen?
Only to a limited extent. With around 2,656 to 2,699 kg/m³ bulk density and roughly 0.35 % water absorption, Seagrass is dense enough for interior applications, but as a calcareous stone it remains acid-sensitive.
Which finishes are available for Seagrass?
The surface finishes available from stock are listed in the »Finishes« block on this page.
Where does Seagrass come from?
Seagrass originates from Turkey, from the Safranbolu-Eflani area in the province of Karabük. The green-brown, fossil-marked effect is typical of this material family.
How do I clean Seagrass correctly?
For cleaning and care, use only pH-neutral natural stone cleaners and soft cloths. Acidic household cleaners are unsuitable for this stone.
Is Seagrass really marble?
Geologically, Seagrass is a fossil-bearing limestone, or a calcareous marble. In the trade it is usually listed in the marble segment because of its look and manner of use.
Seagrass or Jura Gelb?
Jura Gelb appears more yellow-beige and more classic, Seagrass considerably greener, more fossil-marked and more decorative. Both are calcareous and accordingly require more care than granite.
What does Seagrass cost?
The price depends on the batch, thickness, surface finish and fabrication — with natural stone there is no serious flat rate per square metre. Business customers see prices once their B2B account is activated; private customers receive a complete quote through a fabricator near them.
