Onyx

Onyx is a natural stone that belongs to the category of calcite minerals and is a form of banded agate. It is a type of chalcedony, which is a variety of microcrystalline quartz. Onyx is known for its striking appearance characterized by bands of alternating colors. These bands can range from white and lighter shades to deep browns, reds, and greens. The most common and widely recognized form of onyx features black and white bands.

The formation of onyx occurs in the cavities of lava. As water rich in calcium carbonate seeps into these cavities, it can precipitate and create layers of the stone. Over time, the successive deposition of these layers results in the characteristic banded appearance.

Onyx is often used in the creation of decorative items, such as countertops, tabletops, and various ornamental pieces. It is also utilized for jewelry, where its distinctive banding can be showcased in cabochon cuts. Onyx is valued not only for its visual appeal but also for its translucency, which allows it to be backlit to enhance its aesthetic impact.

It's important to note that onyx is a softer and more porous stone compared to some other natural stones like granite or quartzite, which means it requires careful maintenance and sealing to preserve its beauty over time.
