One of five Paragons, the Diamond Paragon is used on the Paragon Platform in the Forgotten Vale to open a portal to the Glacial Crevice. Within, Elven weapons, chests bearing leveled loot, and other gems can be found.
- It can be found on the corpse of Frost Giants in the Forgotten Vale.
- Upon exiting the Glacial Crevice and entering the Wayshrine of Radiance. After exiting the wayshrine, go right though the cave passage going downhill through the cave, the Dragonborn will reach a canyon with a Falmer village inside. Pass through the entire village until one has reached the Glacial Crevice (do not enter). Immediately to the right is a track running uphill. Follow it all the way up to the top to find a glade with a Frost Giant in it, which can be looted for the Diamond Paragon once it's dead. Note that the trackway is immediately to the left upon exiting this area of the Forgotten Vale, if walking in the opposite direction from the Inner Sanctum. There is a Falmer fence at the entrance of the pathway, and there are bodies littering the way. (Take a left and follow the pathway as soon as you exit Glacial Crevice [going towards the Wayshrine of Radience] to reach the Frost Troll.)
