MARBLE / Vratsa

Vratsa

The Vratsa Marble is a small grained calcite rock with a light beige hue and slightly darker veining. The Vratsa marble is ideal both for contemporary and traditional architecture styles thanks to its natural, warm color which is easily combined with a plethora of natural and synthetic materials.

Vratsa marble is used both for interior and exterior applications.
