As ever in Pokemon, not all creatures in Pokemon Let's Go Pikachu and Pokemon Let's Go Eevee evolve and grow through simple battles alone. Some require Evolution Stones, and some of those stones - I'm looking at you, Moon Stone - can be quite hard to find.
Evolution Stones are simply key items in Pokemon Let's Go that when used on certain species of Pokemon force it to evolve. Luckily, we've been slaving away and figuring out exactly where all of Pokemon Let's Go's evolutionary stones are stored so you don't have to. We also list what Pokemon they evolve - but keep in mind your partner Pikachu and Eevee can't evolve - you'll have to catch another.
Most of the stones are fairly straightforward, while the Moon Stone is a little different - and we'll cover that below, in our full list of Pokemon Let's Go evolution stones and how to get them. Let's get going:

Pokemon Let's Go: Evolution Stone Locations
For most stones, there are a few free ones available out in the wild from specific locations, and then you can also buy them from a specific store after that; or if you can't be bothered to go hunting for the items out in the world, you can skip right to the store.
Moon Stone Location
- The Moon Stone can only be found as loot, and fittingly can be found in the Mt. Moon caves area of the map.
- Within Mt Moon, the Moon Stone tends to spawn as a hidden item inside the crater-like features of the area. Watch Pikachu or Eevee - their tails will wag when there's a hidden item nearby.
- The Moon Stone on Mt. Moon spawns once a real-world day, so you can keep farming them over time.
- A Moon Stone can also be found in Saffron City, in the Copycat Girl's house (the top-left house). Check the White Cupboard upstairs.
- The Moon Stone evolves Nidorina into Nioqueen, Nidorino into Nidoking, Clefairy into Clefable and Jigglypuff into Wigglytuff.
Fire Stone Location
- You can pick up a free Fire Stone on Route 8 and in the Pokemon Mansion.
- Otherwise, you can buy a Fire Stone on the 4th floor of Celadon City's mall for 5000 Poke Dollars.
