  • Classic blue: This variety of Kilkenny Limestone is bright blue–grey in appearance, its ancient crinoid fossils providing minor tonal variations to the stone. This variety is suitable for many types of finishes. It communicates a beautiful blue hue when a dry-sanded finish is applied to it and can be brought to a pure black background when honed or polished.

  • Fossil: This special and distinct material is carefully sourced from a narrow seam of fossil beds and features relics of ancient oysters and coral fragments that contrast with a dark background. These large fossils are unique to Irish blue limestone and only found in the Kilkenny/Carlow region of Ireland.

Technical specifications

Irish Blue Limestone was formed some 340 million years ago as a compact crinoidal limestone with a rich fossil content of mainly brachiopods (shellfish) and polyps. Finely dispersed carbon through the stone mass results in a typical blue-grey colour.
