also known as Vratsa Stone, Bulgarian Limestone, Vrachanski Varoval
One of Europe's most admired contemporary limestones, Vratza is a uniformly grey-blue stone from northwest Bulgaria with remarkably low absorption and high compressive strength. Its cool, minimal palette and material consistency have made it a favourite among European designers seeking a premium alternative to Belgian Bluestone at competitive price points. Available in very large slabs from well-equipped quarries.
Type-level physical facts shown. Per-lot lab values (absorption, flexural strength) confirmed at quotation.
Vratza is slightly lighter in tone (silver-grey vs blue-grey), generally less expensive, and available in comparable slab formats. Both share the cool, contemporary palette and high frost resistance.
Yes — it is widely used for ventilated facades, terrace paving and pool surrounds. Its low absorption (under 1%) and frost resistance make it a reliable exterior specification.
