How is the toughness of jadeite best described?

The toughness of jadeite is best described as exceptional due to its unique crystalline structure, which provides a balance between hardness and flexibility. Jadeite is part of the pyroxene mineral group and has a strong interlocking crystal structure that allows it to absorb shock and stress without fracturing easily. This exceptional toughness is one of the reasons jadeite has been historically valued for the creation of items such as tools and jewelry, as it can withstand wear and tear much better than many other gemstones.

In contrast, while some other materials may be categorized as being weak or of average toughness, jadeite stands out due to its ability to resist breaking and chipping, making it highly sought after for both aesthetic and functional purposes.
