The Spectral Jeweller

The Spectral Jeweller is a special Halloween NPC that resembles a Haunter, although it is colored red. It can be spawned using the /halloween command. Upon interacting with the Spectral Jeweller, it will state, "I'm here to exchange your hallowed gems!". However, the means of obtaining hallowed Gems was removed, making the Spectral Jeweller useless.

These "hallowed gems" referred to seventeen different Gems (one for each type except Fairy Gems) that each were found in different Gem structures, which spawned in different biomes that corresponded to each type. Unlike normal Gems, the Gems found in these Gem structures were prefixed with "Hallowed" (e.g., "Hallowed Dragon Gem"). Each hallowed Gem was able to be given to the Spectral Jeweller via right-click, and if all seventeen types of hallowed Gems are given to the Spectral Jeweller, the player was rewarded with an Egg containing a Misdreavus.

Unlike other Pokémon, the Spectral Jeweller cannot be engaged in battle or captured.
