Definition
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone
  
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

All about Granite and Limestone Properties
Know all about Granite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Granite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Granite is Granular, Phaneritic whereas that of Limestone is Clastic or Non-Clastic. Granite appears Veined or Pebbled and Limestone appears Rough and Banded. The luster of Granite is dull to grainy with sporadic parts pearly and vitreous while that of Limestone is dull to pearly. Granite is available in black, grey, orange, pink, white colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Granite are curling, gemstone, laboratory bench tops, tombstones, used in aquariums and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
