Summary of Jade

Jade is a mineral that has been highly valued for thousands of years across many cultures. It is a compact, dense stone that is tough and durable, making it ideal for carving and jewelry making. Jade comes in a variety of colors, including green, white, brown, and black, and can be translucent or opaque.

Summary of Onyx

Onyx is a mineral that belongs to the chalcedony family, which is a type of quartz that is formed by the deposition of silica in the cavities of rocks. It is a cryptocrystalline mineral, which means that its crystals are too small to be seen with the naked eye. Onyx is typically black, but it can also be found in other colors such as white, gray, brown, and green. It has a waxy luster and a smooth, polished surface.
