These were the jewels of Hylia from Legend of Zelda: Ocarina of Time. Kokri Emerald, Goron Ruby, and Zora Sapphire. I just felt like making them because I saw someone else do it and thought, wow, those are cool, I want a set. So, I did. Ironically, the hardest part was the Sapphire, as I needed to turn my perling board diagonally to get it done properly. Weird, eh?
