Pokémon Legends: Z-A – How to Unlock Mega Diancie Through the “Shine Bright Like a Gemstone” Side Quest
The latest update for Pokémon Legends: Z-A has surprised players with an unexpected event—the chance to obtain Diancie’s Mega Stone. Alongside the newly released DLC trailer, Game Freak has launched the “Shine Bright Like a Gemstone” side quest, introducing a fresh bit of lore and one of the most dazzling Pokémon evolutions in the series.
If you’ve been wondering how to get your hands on Mega Diancie, here’s a full walkthrough of the event, along with a few tips for completing the quest efficiently.
How to Start the Diancie Event
To begin, players need to connect online via Mystery Gift in the “Link Play” section. From there, select “Get via Internet” and choose the event titled “Shine Bright Like a Gemstone.” This unlocks the Diancite Mega Stone and triggers the corresponding side quest.
If you haven’t yet claimed your previous event gifts—such as those for Ralts or Gardevoir—you can do so from the same menu. Once you receive the Diancite, the quest will appear in your missions list, marking the start of your journey to meet Diancie itself.
Locating the “Shine Bright Like a Gemstone” Quest
The side quest begins after you obtain the Mega Stone, but you’ll need to have completed several prior side missions to make it available. Once active, it will direct you toward Looker’s Bureau (or “Lucer’s Beiru”), a familiar name for players who’ve experienced Pokémon Omega Ruby, Alpha Sapphire, or X and Y.
Here, you’ll reunite with a character named Emma and her telepathic companion, Mimi. They help you uncover a psychic trail that leads to Diancie’s location. The early part of the quest mainly involves following Mimi as it senses strong emotional or psychic energy radiating from the Diancite.
This section doesn’t feature much combat but offers a charming bit of lore connecting Pokémon Legends: Z-A with older regions and events in the franchise.
Exploring the Lore of Looker and Mega Evolution
One of the most interesting details from this side quest is the return of Looker’s legacy. The quest reveals that Emma, once mentored by Looker, now runs the Bureau in his absence. Through their dialogue, the story expands on the concept of Mega Evolution, referencing Professor Sycamore’s research and the ancient energy that created Mega Stones 3,000 years ago.
There are even callbacks to the ultimate weapon incident and hints that new Mega Stones have appeared as a result of it being fired again in recent history. It’s a neat lore bridge for long-time Pokémon fans and adds emotional depth to what could have been just another fetch quest.
Finding and Battling Diancie
After several short cutscenes and a few character interactions, Mimi will lead you to a location filled with Mega Crystals. Here, you’ll encounter a group of Carbink before finally discovering Diancie itself.
The battle isn’t particularly difficult—closer to a standard encounter than a boss fight—but it’s still wise to bring Pokémon that can handle Rock and Fairy types. Using status effects like Sleep or Paralysis can help speed up the capture process.
Once captured, Diancie joins your party and you can equip it with the Diancite to unlock Mega Diancie, one of the most elegant and powerful transformations in Pokémon Legends: Z-A.
Checking Out Mega Diancie
After completing the quest, head to your Pokémon boxes to locate Diancie. It usually arrives at a high level and can be Mega Evolved once you give it its corresponding stone. The design looks stunning, and its special attack and speed receive a significant boost—making it an excellent option for both casual play and competitive setups.
For players looking to expand their collection or experiment with rare forms, many turn to in-game trades or community exchanges. Some even explore ways to buy shiny Pokémon Legends ZA creatures from trusted trading platforms to build themed teams. It’s a fun alternative for players who enjoy collecting shiny variants but don’t have time for the lengthy hunt.
Completing Your Shiny and Mega Collection
Mega Diancie’s event adds more than just another legendary—it enriches the broader ecosystem of Pokémon Legends: Z-A by tying lore, nostalgia, and gameplay progression together. If you’re the kind of player who enjoys collecting rare or exclusive Pokémon, this quest is a must-do.
Meanwhile, some players interested in rare shiny variants might also notice Legends ZA Shiny Pokémon for sale from third-party game service providers like U4GM, where trainers often look for specific forms to complete their living Pokédex. While in-game hunting is always the most rewarding experience, options like these exist for collectors who prefer to focus on battles and team-building instead of repetitive farming.
The “Shine Bright Like a Gemstone” event is a small but memorable addition to Pokémon Legends: Z-A. It delivers an enjoyable mix of light storytelling, nostalgia for classic characters, and one of the most iconic Mega Evolutions in the series.
Whether you’re after lore connections, a stronger Fairy-type for your lineup, or simply want to see Diancie sparkle in battle, this quest is worth completing. And with new events likely on the way, it’s the perfect time to revisit Lumiose City and see what other secrets might still be hidden beneath its shining surface.
