Ruri Rocks episode 4 recap

Ruri Rocks episode 4, titled Study of Sands, saw Nagi Arato ask Ruri Tanigawa to study each sample of sand thoroughly to identify the source of sapphire in the river. While Ruri wished to take shortcuts, Nagi assured her that the tedious task of looking through the sand was a shortcut itself.
As Ruri kept looking through the sand deposits for sapphire, she came up with a new idea to reduce her workload. By using a magnet, she could pull out magnetic rocks, leaving her with less sand to look through. Amidst this, Imari was progressing further with her research.
What to expect from Ruri Rocks episode 5?

Ruri Rocks episode 5, titled Worlds Seen and Unseen, will most likely see one of Ruri Tanigawa's classmates join her during a sapphire hunt. As seen in the anime, while Ruri was busy going to the river to look for sapphire, her classmates Aoi Kasamaru and Shouko Seto could not ignore her passion for her hobby.
While Aoi Kasamaru merely wished to spend time with her friend, Shouko Seto seemed interested in what Ruri was up to lately. With that, the anime's next episode could see Shouko keep an eye on Ruri and eventually join her.
