Reading this is sure to make you fall even more in love with Ruri no Houseki!
【Special Feature】
In Ruri no Houseki, the minerals featured are primarily those with confirmed specimens found in Japan. Therefore, for this book, we specifically requested that the specimens introduced be (as much as possible) from Japan! Thanks to Mr. Watanabe's efforts, this book allows you to truly appreciate the diversity of minerals found in Japan, even if their crystal sizes may not rival those from other countries.
