Marianna Grey is a very hard Sandstone (similar to Greywacke), which is suitable for interior and exterior use: as cut to size material for facades and floors, for terraces and garden paths.
It can be used for window sills and stairs, for wall claddings and copings.
Stones with irregular form or split surface are perfect for gardening and landscaping.
The variety of surfaces and finishes leave a lot of scope for the creativity of architects and builders.
