Krukowski Stone Company is a Wisconsin quarrier and manufacturer of natural stone products, specializing architectural full and thin building stone, cladding panels, countertops slabs, paving stone, landscaping stone and more!  We are a premier natural stone fabricator in Wisconsin.

Our quartz-cemented sandstone encompasses the following products: Apple Creek™, Cambrian Cream™, Chestnut™, Glacier Bay™, Highland Brown™, and Sandy Creek™. All of these products come from the same quarries. The Chestnuts are fieldstone boulders that occur in the indigenous topsoil that lies atop our quarry. Over millions of years these stones broke off of the top of the quarry and were then moved by ancient glaciers, where they absorbed a dark chestnut color from the native soil. Once all Chestnuts are removed from an area the only way to produce more is the tedious process of opening up more land. The Apple Creek™ occurs in the top layers of the solid quarry. These stones are in thinner layers and contain higher levels of magnesium which gives the stone a crimson coloring with abundant veins. Deeper in the quarries occur our Sandy Creek™ and Highland Brown™ materials. These are cut from the same rock formation, but the Sandy Creek is the inside split-face light colored stone and the Highland Brown™ displays the natural exterior of the stone, including the weathered edge, seam-face and bed-face material. And when the large blocks of the Sandy Creek™/Highland Brown™ are sawn into slabs the sawn product is named Cambrian Cream™.

Krukowski Stone Company and its subsidiaries own over 1,000 acres of quarry-able land in the Town of Guenther, Marathon County, WI.

Just one-half mile from our quartzite sandstone quarry lies our Aqua Grantique™ quarry; the Aqua Grantique™ is a Hornblende Gneiss. The dark green to black minerals that make up the majority of the rock is an amphibolite. This type of rock has been metamorphosed into another type of rock by high pressures and/or temperatures. Before this transformation occurred the original rock was probably either a dark-colored mudstone made up of volcanic particles derived from a volcanic ash-fall; or a basalt (basalt is an igneous rock, formed by lava cooling at the Earth’s surface). In either scenario, the Aqua Grantique™ formed from a volcanic rock that was later metamorphosed. What about the minerals in the narrow cracks and fissures? The white to olive green colored minerals in the cracks and fissures are a mixture of quartz, calcite, and pyroxene. The quartz and calcite are both whitish in color. Pyroxene is dark black in color. Also found in small areas throughout the rock (both in the cracks and in the amphibole-rich parts of the rock) is a gold-colored mineral, pyrite, also known as fool’s gold. This material is very erratic in structure and can be difficult to process - but holds everlasting beauty.
