Features of Mashhad Pearl Granite Stone

This type of stone, also known as marble or granite, are a type of acidic internal igneous rock. For this reason, its texture has medium to large grains and contains quartz (mountain ore) and feldspar, mica, and parts of other minerals. Depending on the minerals that make it up, the stone comes in a variety of colors, from white to gray.

Mashhad Pearl Granite is one of the heaviest stones with a density of 2.75 grams per cubic centimeter and also has a high compressive strength. Medium volume mass, weather resistance, water absorption below 1%, very low porosity, high color diversity, frost resistance are other characteristics of Mashhad granite stone. It belongs to the white granite family.
