Emerald Pearl granite

Description of colouring and granulometry: dark green, coarse-grained plutonic rock of a black to dark olive-green colour with a regular and uniform structure.
The characteristic colour change effect derives from the fracture and the reflection of the light falling on the anorthoclase crystals which have a lamellar form. The
reflecting light follows the different angles depending on the cutting plane. It is quarried in the south-east of Norway, in the Larvik region, in Klastan.

Production / availability: medium-good.

Finitions-textures: smooth, polish, flamed, clived.

Prevailing applications: interior and exterior.

Other commercial names: Emerald Pearl, Dark Larvikite, Dark Labrador.
