The formation of onyx begins in the large, vast limestone caverns, where the cavern’s dripstone deposits form stalactites, stalagmites, and other formations, filling the otherwise void space. Stalactites and stalagmites are developed over time as the soft droplets of water are combined with the evaporation process creating a more dense calcium carbonate. The buildup of calcium carbonate incrementally forms a chemical sedimentary stone, known as onyx.
What does onyx look like?
Onyx is crystalline stone, is often translucent, and according to the Marble Institute of America, onyx is “strongly banded and colored in browns to yellows and clear.” The degree of translucency of onyx varies from slab to slab and is dependent on the crystal structure, color, thickness, and surface finish. Onyx, like most limestone, will recrystallize in time, often enhancing translucency.
What are some creative onyx applications?
Because onyx is typically translucent, many designers and artists find that the stone is ideal for backlighting. From creative wall installations to cocktail bars, onyx is lighting up the design world.
