Overview[1][2]
Glass Diamond is a Mythical fish found in the Overgrowth Caves. Its primary use is for obtaining the Crystalized Rod, which two are required.
The Glass Diamond is a Mythical fish found in Overgrowth Caves, the second section of Northern Summit. Despite its high rarity, it makes for an easy catch, moving slow and steady across the fishing bar. The Glass Diamond (two players with one each) is also required to obtain the Crystalized Rod. When hooked, an exclamation icon will pop above the player's head, and a bell sound is played - as with all Mythical fish.

What does this mean?
Fisch's in-game currency. A fish's value is its average sale price in C$ at average weight. A rod's value is its listed C$ price, which may be only one part of a crafting requirement. These are game reference figures, not trading consensus. Values are not comparable across games.
