Labrador Antique Granite is an expensive coarse grained natural stone quarried since 1996. This stone has a high resistance to both staining and scratching. The coloring is unique with a deep brown background, large crystals, and highlights of reflective blue to purple crystals.
Labrador Antique Granite is classified into two qualities before leaving the quarry: 
GLA 1st choice has a brown background with clear blue to purple crystals. There could be red, brown, black, white,or green lines and some small black spots in the structure. 
GLA 2nd choice is similar to the above in color and crystals but may contain larger veins and more black spots. It could also be more open in structure than first choice. 

The level of pitting varies between slabs. There are also variations in the brown tones and crystal size so it's always best to view your stone.
