The locations to all 5 Paragons in The Elder Scrolls V: Dawnguard DLC for Skyrim.
There are 5 Paragons: Amethyst, Ruby, Sapphire, Emerald, and Diamond. Each can be found on the corpses of individual Frost Giants.
Amethyst - 0:15
Ruby - 0:45
Sapphire - 1:20
Emerald - 1:45
Diamond - 2:08
Across the river of the Frost Giant that provides the Sapphire Paragon is the Paragon Platform. It is composed of two columns and a Paragon Socket. When at least one paragon is obtained, they can be inserted into the socket creating a portal to an area with varying treasures depending on the Pargon. The value of the treasure seems relative to the value of the Paragon inserted.
One of the treasures includes Auriel's Shield which can be found using the Ruby Paragon. For tutorial: http://www.youtube.com/watch?v=-617eg_2AQk
