This book contains valuable information about the different mountains in Neo Valley where chrysanthemum flower stones are found. Ishihara also describes the various types of foundation stones and the mineral formations--the "flowers." He provides descriptions of two chrysanthemum flower stone museums and the mum stone collections held by 15 collectors including him self. The book, in many ways, summarizes what he has learned throughout his lifelong association with these stones. This book can be used as a reference to identify the mountain in Neo Valley that a particular stone originated.

Ishihara is a well-known, long-time collector and connoisuer of Neo Valley chrysanthemum flower stones. He has published two earlier books on these stones, one in 1986 and another in 2000.
