Sandstone Blocks

Sandstone is formed by the hardening of small grains of older, fragmented rocks ranging in size from 1/16 mm to 2 mm, under pressure over time and a mixture of quartz, calcium carbonate or iron oxide, which acts as cement. The amount and type of minerals in the rock give the stone its natural color over time. Due to the low hardness of the sandstone, it can be extracted from the quarry in smaller sizes compared to other natural stones. At this link of Stonecontact.com, you can find rough blocks of sandstones in different colors, their owners and the most reasonable prices, which are mined in various parts of the world.
