Choose almost any type of
stone for your project.

Natural stone has a long and storied history as an architectural element. Modern architects and developers view natural stone as a “go-to” material, just as their forebears did. Its durability, versatility, and aesthetic appeal do not go out of style.

Trimstone® panels are typically composed of granite, limestone, marble, or travertine, but they are not limited to this group of stones. It is important to understand that each of these materials has unique characteristics that must be matched to the anticipated conditions of the client’s unique project. Given final material determinations, individual panels can be as large as 60” x 120”.

Stones Types

Stone Types


Granite is an igneous stone with clearly visible grains. It is formed through the slow crystallization of magma beneath the surface of the Earth. Granite is mainly composed of quartz and feldspar with relatively small amounts of mica and other minerals. These minerals produce the red, pink, gray, and white color values that are typically associated with this resource.


Marble is a metamorphic stone. It is formed when limestone is subjected to both heat and pressure and is primarily composed of calcite (CaCO3). Typically, clay minerals, micas, quartz, pyrite, iron oxides, and graphite are also present. Given metamorphic conditions, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals, which is marble.


Limestone is a sedimentary stone that is primarily composed of calcite. It typically forms in marine waters that are clear, calm, warm, and shallow. As a biological sedimentary rock, limestone results from the accumulation of shell, coral, and organic debris.


Travertine is a relatively dense, banded, and layered stone composed of calcium carbonate. It is a variety of limestone formed by the evaporation of river and spring waters. Visually, this material displays as a beige to brown color. It is often pitted with small irregular holes and random dark graining.
