Agate, on the other hand, is a kind of gem composed of microcrystals. The common colors are gray, brown and red. Agate is rich in color and natural in texture. Because of its high hardness and easy processing, it is often used to make jewelry, ornaments and handicrafts.
Although huanghuashi and agate are precious stones, there are obvious differences in chemical composition, color and appearance. The color of yolk stone is bright yellow, while the color of agate is more diverse. In addition, Huanghua stone is soft and easy to be damaged, while agate is hard and durable.
Therefore, although Huanghua stone and agate are beautiful gems, they belong to different ore categories and have different chemical compositions and characteristics. This also shows the importance of gem identification and classification to ensure the correct identification and use of gems.
