Indiana Limestone Colors and Grades
The Indiana Limestone Institute of America (ILI) classifies Indiana Limestone into two colors and four grades based on granular texture and other natural characteristics. When specifying Indiana Limestone it is necessary to identify both the color and grade required or desired for a project as well as the surface finish to be applied to the stone. Contact us for more information about Indiana Limestone color choices or to schedule an appointment to see color options in person.
Indiana Limestone Color Classification
COLOR DESCRIPTIONS
Buff — varies from a light creamy buff shade to a brownish buff.
Gray — varies from a light silvery gray to shades of bluish gray.
INDIANA LIMESTONE GRADE DESCRIPTIONS
The ILI classifications are based on the degree of fineness of the grain particles and other natural characteristics which make up the stone. The structural soundness of each of the grades is essentially identical.
As a natural product, Indiana Limestone contains at least a few distinguishable calcite streaks or spots, fossils or shelly formations, pit holes, reedy formations, open texture streaks, honeycomb formations, iron spots, travertine-like formations and grain formation changes. However, through the years, one of the pleasing features of Indiana Limestone which has made it adaptable to the various architectural styles is that, as these do not exist in large, noticeable concentrations from stone to stone, one piece looks very similar to another with no discernable pattern of these natural characteristics. For this reason, Indiana Limestone does not lend itself to pattern blending as do stones which have characteristics such as specifically pronounced veining which exists from stone to stone.
| 1. Select | Fine to average-grained stone having a controlled minimum of the above characteristics. |
| 2. Standard | Fine to moderately large-grained stone permitting an average amount of the above characteristics. |
| 3. Rustic | Fine to very coarse-grained stone permitting an above-average amount of the above characteristics. |
| 4. Variegated | An unselected mixture of grades 1 through 3 permitting both the buff and gray colors. |
