Each one of our stones are extremely unique and have been used throughout our history. Stones have been the essential tool and resource of humans dating back to the earliest civilizations. Here at Lexell Stone we are bringing it back to the basics and using these same stones to create one of a kind timepieces.
Granite is an igneous rock and is formed from magma. Granite is usually found in the continental plates of the Earth's crust. The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
Granite is one of the rocks most prized by climbers for its steepness, soundness, crack systems, and friction. Well-known venues for granite climbing include Yosemite, Patagonia, and the Cornish Coast.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through heating and pressure. It is the finest grained foliated metamorphic rock. Because slate was formed in low heat and pressure, compared to a number of other metamorphic rocks, some can be found in slate; sometimes even microscopic remains of delicate organisms.
Slate has been used by civilizations throughout history. In the Mayan civilization it was use to fashion stelae
and as a whetstone
to sharpen knives. It's was used extensively in tools and in home construction.
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression. When sandstone is cemented to quartzite, the individual grains recrystallize along with the former cementing material to form an interlocking mosaic of quartz crystals.
Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. During the Stone Age quartzite was used as an alternative to flint. Today it is used as a decorative stone.
