No on is exactly sure where the Hidden Jewel is located. Even if they did find it, they wouldn't be able to find it again later on. The Hidden Jewel is a small cave make of branches and thickets, hidden within Nigotta. Inside the cave, is a small fresh-water pond, with several koi fish lurking in the water. There is a small crack in the ceiling right above the pond, so when the light reflects on it, it shimmers like the night sky.
