Black and Tan Granite Coaster

Set of 6 high-gloss, cork-back plastic coasters with an image of black and tan granite. Granite is currently known only on Earth, where it forms a major part of continental crust. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock. See matching sandstone coaster, marble coaster, paper coaster, paper cocktail napkin and cloth napkin. See the entire Father’s Day Coaster collection in the FOOD/BEV | Coasters section.
