The Cast Tec Bolection 50″ Nero Marquina Marble Fireplace Surround combines a clean architectural bolection profile with the dramatic appearance of Nero Marquina marble. With its deep black background and contrasting white veining, this natural stone surround creates a bold and sophisticated focal point in both contemporary and traditional interiors.
Nero Marquina originates from the Basque region of Spain and is recognised for its rich black colouring crossed by naturally occurring white veins. The pattern and intensity of the veining can vary considerably from one piece of stone to another, meaning every fireplace surround has its own individual character.
The restrained Bolection design works particularly well with such a striking material. Its simple projecting profile frames the fireplace opening without excessive ornamentation, allowing the natural contrast and movement within the marble to remain the dominant visual feature.
The mantel has a shelf length of approximately 1275mm / 50.19″ and an overall height of 1095mm, giving it compact and well-balanced proportions suitable for a wide range of chimney breasts and room sizes.
The internal opening measures approximately 915mm wide x 915mm high, creating a classic square format that can be coordinated with suitable fireplace inserts, chambers and fire arrangements. A 25mm internal rebate provides additional depth for integration with the wider fireplace installation.
The shelf itself measures approximately 142mm deep, helping maintain the relatively shallow, architectural appearance of the Bolection profile.
With its black marble, contrasting white veining and simple proportions, the Cast Tec Bolection Nero Marquina Marble Fireplace Surround is particularly suited to interiors where a strong, design-led fireplace feature is required.

Expert Insight
Nero Marquina is especially effective in a simple bolection design because the restrained profile allows the marble’s natural contrast to become the main feature. The black background and white veining can create a much stronger visual statement than lighter stones, making it particularly well suited to bold, design-led interiors.
Suitability
The Cast Tec Bolection 50″ Nero Marquina Marble Fireplace Surround is well suited to contemporary living rooms, luxury interiors, period properties with darker detailing, and fireplace schemes where a dramatic natural marble focal point is required.

Nero Marquina is a natural marble, so colour, veining, pattern and markings can vary considerably between individual surrounds. Where the exact appearance of the stone is important, photographs of the available surround should be viewed before ordering.
