Markarth: The Treasury House, in an end table in Thonar's bedroom, which is down the hall on the left from when you enter the front door. You may need to pick an apprentice-level door, but no one reacts.

College of Winterhold: Arch-Mage's Quarters. Access may be gained at the end of the quest Under Saarthal.

Reeking Cave or Thalmor Embassy: Prior to patch 1.4, the stone is located in the Thalmor Embassy in Elenwen's Solar on the second floor. After patch 1.4, inside Reeking Cave and next to a corpse in the back. Acquiring the gem during the Diplomatic Immunity quest is advised, since the easiest way to access the cave is through your escape near the end of that quest. However, it is still possible to access Reeking Cave without doing that quest.
Pinewatch Bandit's Sanctuary: In a house west of Helgen, there is a secret hideout accessible from the basement (you have to push a button on the wall to open the bookshelf). The gem is found in a locked room in the Bandit's Sanctuary.
Dark Brotherhood Sanctuary: On the dresser in Astrid's room. It is still accessible after the Death Incarnate quest; however, the game may freeze when you try to enter the Sanctuary after completing that quest.
