Indiana Limestone is an oolitic limestone that is found near the surface along a line generally extending from Northwest Monroe County into Lawrence County, commonly known as the limestone belt. Indiana limestone has been called Salem stone and Bedford Stone or Bedford Limestone. Indiana limestone is recognized for its natural beauty, color, versatility, and workability. Indiana limestone is generally designated one of three colors:
- Buff – a creamy white or tan
- Grey – commonly a blue grey
- or Variegated – both buff and grey found in the piece or field of the limestone surface.
Indiana limestone is also graded based on the grain of the stone and the number of imperfections found in a block or slab. Obviously, the finer the grain and the fewer imperfections demand a higher price. However, the ultimate buying decision is typically based on the overall “look” desired by the customer, the size of the individual pieces, and fabricator production methods.
