Silver Pearl Granite
Return to granite samples page.
Synonyms: Blue Pearl SP, Blue Pearl Silver
Location: Silver Pearl granite is quarried in Norway. It is available in two types: Silver Pearl® and Silver Pearl® Building.
Description: Silver Pearl granite is a commercial name for a coarse-grained, dark grey granite with large, shiny pearls. iridescent syenite (larvikite) of the Permian period. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a syenite.
A small sample of Silver Pearl granite is usually representative not having a wide variation in colour and veining however swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Silver Pearl granite is frost free and polish constant.
When processed for flooring some tiles should be rotated 90° to get an homogeneous surface.
Silver Pearl® and Silver Pearl® Building colouring and quality are the same however Silver Pearl® Building is cut at a 45 degree angle to increase efficiency and lower prices. Such cutting is possible due to the shape and size of crystals. Uniform colour, competitive pricing and high availability makes Silver Pearl® quite unique and a perfect project material.

Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
Syenite: A coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts (<5%). The feldspar component of syenite is predominantly alkaline in character (usually orthoclase). Plagioclase feldspars may be present in small quantities, less than 10%.
