Crimson Agate is a unique Adventure item found only in a single region of Genshin Impact's world of Teyvat. The only place you can find it is in the snow-covered Dragonspine mountain. This special item is the only region's version of Oculi, sharing many similarities to them, but also having several drawbacks, such as not having a related resonance stone.
Crimson Agate is a bright red gem that you can acquire in exchange for useful rewards, similar to how Statues of the Seven work in other regions. Here's how and where to find Crimson Agate in Genshin Impact.

How to Get Crimson Agate in Genshin Impact
Crimson Agate gems can be found everywhere in the Dragonspine region, both out in the world and in chests. Interestingly, chests that contain them will not show up on the player's minimap, but you can discern them by the red glow that they emit.
There are 80 levels that you can get normally, according to the list above. If you offer them all up to the Frostbearing Tree, you will get it from Level 1 to Level 9 with them alone. But there are still others, and that's where Crimson Wishes comes in.
After leveling up the Frostbearing Tree to Level 8, there are a number of repeatable World Quests that you may get. Every Monday and Friday, five Crimson Wish quests will spawn around Dragonspine on your server, and completion each of them rewards you with one extra Crimson Agate.
If you wish to get more Crimson Agate than the required quantity, make sure you don't level your Frostbearing Tree to Level 12. That's because once it's reached that level, the Crimson Wish quests become unavailable, while you can keep any extra Crimson Agate you've collected.
