What's The Difference Of Marble And Onyx?

Sep 02, 2020

Marble is mainly composed of calcite, limestone, serpentine and dolomite. The main component of marble is calcium carbonate, which accounts for more than 50%. Because marble generally contains impurities, and calcium carbonate is affected by carbon dioxide, carbides, and moisture in the atmosphere, the marble is also prone to weathering and dissolution, and the surface quickly loses its luster.

Onyx is naturally produced, and after processing, it becomes a beautiful stone with fine and smooth, bright color, tough texture, and stable chemical properties. It can be classified as jade (that is, all beautiful stones are onyx). The onyxwe usually talk about is actually mainly nephrite and jadeite (due to the difference in hardness between the two). Nephrite refers to onyx composed of tremolite-actinolite minerals, namely white onyx, clear onyx, jasper, topaz, etc.; Onyx Jadeite refers to onyx from Burma with properties similar to nephrite. Diamonds, red sapphires, agates, corals, coal crystals, tortoise shells and the like are "organic gems." People's requirements for soft jadeite are relatively consistent, that is, the texture is hard and dense, and the color is bright and bright.
