Ruri Rocks episode 3 recap

Ruri Rocks episode 3, titled The Lost Planet, saw Ruri visit Nagi's university laboratory to check out her paper on pyrite. To Ruri's surprise, her contribution was mentioned on the paper. Later, Ruri met Nagi's junior, Imari, who was also a mineralogy graduate. The anime later saw Ruri find a treasure map indicating only mining regions. Hence, the three left for the location to find new minerals.

During their search, it became evident that while Imari had a lot of knowledge about minerals, she could not identify minerals due to a lack of experience. The anime episode saw the three find Fluorite, a mineral that emitted beautiful colors when hit with black light. Imari wanted to contribute to Nagi's paper, but Nagi motivated her to be the lead author instead.

What to expect from Ruri Rocks episode 4?

Ruri Rocks episode 4, titled Study of Sands, will most likely see Imari complete her paper on the Fluorite mine and show it to Nagi and Ruri. Soon after, the anime could see the three going on another mineral hunt. However, this time, as hinted at by Nagi in the previous episode, they might go after Sapphire.

Additionally, as hinted at by the episode title, the anime episode could share some interesting information about sand.
