Genshin Impact players need to collect resources to ascend and level up characters. But some resources are very rare and hard to collect. Here are the top 10 rarest resources in Genshin Impact and the best places to get them.

#1. Sango Pearls

Sango Pearl is the local resource in Inazuma. It's small and rare. So, it's very hard to spot and find this material. You can collect only 54 pearls per 48 hours. Here are the best places to gather this resource.

  • Watatsumi Island is the main island to find Sango Pearls, especially Mochizuki at the Sagonomiya Shrine.
  • Enkanomiya has 10 pearls to collect every 2 days.

You need this resource to ascend characters from Inazuma, including Kokomi.

#2. Crystal Marrow

Crystal Marrow is one of the rarest materials in Genshin Impact 2.5. There are only 66 crystal marrows available to collect every 48 hours. This kind of material spawns almost solely on Yashiori Island.

You don't need to use the Geo character or the sword, claymore, and polearm to collect the ore although it looks like an ore. Players only need to get close to the item and collect it directly.

#3. Cor Lapis

Cor Lapis is a rare item in Liyue. You should use a Geo or claymore character to break this ore from the ground. There are some routes of Cor Lapis in Cuijue Slope and Mt Aocang. You can also buy it from Changshun.

There are 142 ores to collect every 48 hours. When you go exploration with Qiqi and Yanfei, you can locate this ore more easily thanks to their passive talents.

#4. Luminescent Spines

Luminescent Spines spawn sparsely across the open world. You need to catch fireflies all around Teyvat to gather them. Dawn Winery is the hot spot of fireflies with a higher rate of collectibles. You can catch only 26 fireflies every 2 days. Besides, you should use Sayu to approach the fireflies quietly to catch these flying insects.

#5. Qingxin

You need a lot of Qingxin flowers to ascend many characters from Liyue, such as Xiao, Ganyu, and Shenhe. But there are only 99 flowers every 2 days to collect. Moreover, these flowers often grow on high mountain peaks.

You should go to Jueyun Karst and Wuwang Hill to pick up the flower. Or else, find Herbalist Gui to buy 10 more flowers every three days. Besides, the NPC Qinglian at Stone Gate also gives you three flowers for free.

#6. Philanemo Mushrooms

Philanemo Mushroom only grows in Mondstadt. You need this resource for character ascension and cooking. The best spawn locations of this mushroom are the City of Mondstadt, Dawn Winery, and Springvale. You can collect 50 philanemo mushrooms every 48 hours.

#7. Crystal Cores

Crystal Core is also a rare resource scattered all around Teyvat. You need to use Sayu to approach Crystalflies or they will fly away. It's hard to catch a couple of Crystalflies at once. Besides, their spawning rate and density are pretty low. They often fly around Statues of the Seven.

#8. Violetgrass

Violetgrass is often hard to harvest. These flowers usually grow on high mountain cliffs. So, you need to climb to those vertical and dangerous cliffs to collect them. Moreover, it's hard to spot this flower from the ground. You should meet Herbalist Gui in the Liyue Harbor and Verr Goldet at Wangshu Inn to buy some.
