The Stone Emporium is Lumiose City’s dedicated shop for Mega Stones and evolution items in Pokémon Legends: Z‑A. Its inventory expands as you progress through the main story, with early staples unlocking around Mission 10 and late-game stones arriving after Mission 39.

Stone Emporium location (Lumiose City)

Head south from Prism Tower in central Lumiose City and continue straight down the main avenue; the Stone Emporium sits in the southern part of the map. You’ll visit early in the campaign and can return anytime as new items are added.

When the Stone Emporium stock unlocks

  • Core Mega Stones appear during Main Mission 10: “The Secrets.”
  • Additional high-tier stones are added after Main Mission 39: “The Infinite Z‑A Royale.”
  • Some entries (like Gengarite) become available once you’ve obtained the relevant story stone (e.g., Absolite).

Prices fall into clear tiers: 50,000, 70,000, or 100,000 Pokédollars depending on the stone.

These are the Emporium’s confirmed Mega Stones and price tiers. Additional Mega Stones are obtained through story battles or shard exchanges rather than cash purchases.

What else the Stone Emporium sells

The shop also carries evolution items beyond Mega Stones. Late in the story (after Mission 39), more evolution stones, such as the Shiny Ston,e are added to the catalog.

Other ways to get Mega Stones

  • Victreebelite (Mission 13)
  • Beedrillite (Mission 16)

Quasartico Inc. shard exchanges

After Mission 10, Quasartico Inc. lets you trade Mega Shards—found as purple destructible clusters around Lumiose City—for specific Mega Stones. Costs vary by stone (commonly 180, 240, or 360 Mega Shards). Examples:

Mega Stone Shard cost
Audinite 180
Lopunnite 180
Manectite 180
Sharpedonite 180
Aerodactylite 240
Clefablite 240
Dragalgite 240
Eelektrossite 240
Lucarionite 240
Skarmorite 240
Aggronite 360
Alakazite 360
Drampanite 360

More stones open for exchange as you advance the story, including sets that unlock around Missions 19, 20, 25, 31, and post‑Mission 39.

Time-limited and competitive rewards

  • Gardevoirite is distributed via Mystery Gift during a limited window.
  • Greninjite, Delphoxite, and Chesnaughtite are tied to early Z‑A Battle Club ranked seasons and require reaching a specified rank.

If you miss a seasonal reward, watch for future rotations; some items reappear later through other methods.

Paying for stones: earning Pokédollars

The most reliable way to fund Emporium purchases is by battling trainers at night. As your team and rank improve, this scales quickly enough to cover the 50,000–100,000 Pokédollar tiers without excessive grinding.

How Mega Evolution works once you have a stone

  • Equip the correct Mega Stone on the matching Pokémon.
  • Build the Mega gauge by landing attacks in battle.
  • Trigger Mega Evolution with the right stick when charged.
  • The form lasts about a minute, then enters a cooldown and can be used again.

Stones are permanent and can be reused across battles as often as you like.

The quickest path to early Mega Evolutions is a mix of Main Mission clears for guaranteed drops, shard exchanges for specific targets, and a few cash buys from the Emporium once Mission 10 is complete. Keep checking the shop after major story milestones—its late additions cover popular starters and heavy hitters you’ll likely want for the endgame.
