Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
  
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.

Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
  
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.

All about Limestone and Luxullianite Properties
Know all about Limestone and Luxullianite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Luxullianite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Luxullianite is Granular, Phaneritic. Limestone appears Rough and Banded and Luxullianite appears Veined or Pebbled. The luster of Limestone is dull to pearly while that of Luxullianite is dull to grainy with sporadic parts pearly and vitreous. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Luxullianite is available in black, grey, orange, pink, white colors. The commercial uses 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 and that of Luxullianite are creating artwork, curling, gemstone, laboratory bench tops, tombstones.
