Crystal Star Locket

The Crystal Star Locket was given to Princess Serena by her mother Queen Serenity when her original Sailor Locket was destroyed by the Cardian Racy. Once the Silver Crystal is merged with this item, it is activated with the phrase "Moon Crystal Power" and allows Serena to transform into Sailor Moon.

This locket also replaced Sailor Moon's healing ability which was originally performed with her Crescent Moon Wand and is activated with "Moon Crystal Healing Activation". The Crystal Star Locket was damaged during the Sailor Scouts' first encounter with the Heart Snatchers, when the Daimon Mikuzi, that targeted Raye Hino for her Heart Crystal, bit it, cracking the outer casing, and de-activating Sailor Moon's transformation. From then, Serena was unable to use it to transform.

The Crystal Star Locket was succeeded by the Cosmic Heart Compact.
