Ruri Rocks

Ruri, a high school girl with an interest in jewelry and accessories, becomes involved in mineral collecting, exploring mountains, rivers, and caves to learn about the field. The first volume includes descriptions of various minerals such as quartz and garnet, as well as minerals like pyrite and fluorite. Ruri uses specialized tools like panning dishes, hammers, and topographical maps to aid her in her collecting endeavors. This manga draws from the author's experience in mineralogy.
