Once you've acquired the Magic Key, you can head towards the Sunstone's location by talking to the Sage in Tantegel Castle's basement on the lower right side of the castle garden.
Head to the back of the castle and go outside. From there, go right then south down the stairs to reach the castle's basement level. Speak to the Sage here and he'll give you the Sunstone.
