The book introduces many kinds of gemstones and minerals, showing their beauty through pictures, and also describes their physical properties and crystal characteristics in detail. This can not only increase our knowledge, but also cultivate children's interest in natural science. Moreover, the content in the book is easy to understand and is very suitable for reference by general gem lovers and professional technicians.
The classification entries are clear, the illustrations are diverse, and the science popularization is good. It can be used as a popular science encyclopedia. However, there is very little introduction to specific gemstones, only a short introduction to the physical characteristics of the stone. Slightly less readable.
