Hi, I saw your question in Crystal Story II about the Sapphires. You can find them by fishing in the Fishing Spot, located to the left of Crystalia, in one of the islands (The islands are accessible/unlocked once you defeat the Dargon boss in the Abyss.)Hope this helps you! If you got an answer already, ignore this comment, and have a nice day.
Thank you. Actually I caught one sapphire here; but it seems that I can catch a rare only once – I tried 10-20 times more, but didn’t get even one rare. It’s sad that there is only 1 sapphire.
