Black is the new black… at least as far as stone for interiors goes. We’ve fallen in love with two stones that, depending on treatment they receive, can create many different looks.

You are likely familiar with granite, which has long been a popular choice for kitchens and baths. Formed when magma (molten rock) cools, granite is an igneous stone that can contains a blend of materials, blend of minerals joined together such as quartz, feldspar, iron and mica. Often used in its polished states, it has recently become available in a variety of alternate finishes, such as honed, antiqued, or leathered granite. The muted color of these finishes look both timeless and completely modern, lending the stone a more organic feel. Polycor, owner of over 25 quarries in North America, offers several varieties of natural stone, including the popular Cambrian Black and St. Henry granite, in a range of textures from polished to flamed and everything in between.

More under the radar is soapstone, which is a metamorphic stone, formed by a combination of heat and pressure. Polycor’s Alberene Soapstone is a high-density steatite suitable for architectural applications. Specific geologic occurrences and conditions have to exist in order to produce this type of stone, and Alberene Soapstone is the only deposit of its kind on the North American continent. Soapstone is the go-to surface for chemistry labs, and the same qualities of resistance to both heat and acid make it a great choice for residential kitchen counters. Soapstone has a softer and more subtle color and, unlike granite, cannot be polished but a low luster can be achieved with a wax treatment.

In honor of their favorite black stones, Polycor is hosting a party for members of the trade at Chicago Field Museum on April 20. The quarrier chose the venue for its grand architectural setting and impressive exhibits, which range from Stone Age cave paintings to precious gemstones. The building itself was faced entirely in Polycor’s White Cherokee Georgia marble when first constructed in 1914. Dubbed Black Equinox, the party will offer designers, architects and stone professionals a chance to network and experience black stones in all their finishes and textures. Polycor will also honor four influential women in the stone industry. (Shhh, names to be revealed at the party!) To learn more about attending the event click here.

The best way to celebrate these lovely stones, however? Enjoying the beauty they bring to any living space. See our favorites in the slideshow.
