Daphne Blake's locket is a magnifying glass-shaped locket/necklace. Daphne found it in the caves of Crystal Cove. It contains a picture of Brad Chiles and Judy Reeves, two members from the original Mystery Incorporated who were in a romantic relationship; It is known that Brad gave it to Judy. (Escape From Mystery Manor)

The locket will play a tune when it is opened, which Professor Pericles recognized and called a "little theme song."

Judy lost it in the Crystal Cove Caves when she gave it to Professor Pericles to open a box containing a piece of the Planispheric Disk and traps were sprung that caused Pericles to drop it into rushing water. (All Fear The Freak)
