As you progress through Dune Awakening you will no doubt start to find yourself looking for Diamondine Dust. That's because this rare material is required to build your ornithopter.
In addition to being required for the ornithopter, it is also a component in other crafting recipes such as vehicle hulls and short blades.
This is a very restricted resource but there are a couple of places you can source it reliably, so worry not.
Farming It In Mysa Tarill
Mysa Tarill is located just south east of the Eastern Shield Wall and is accessible by driving alongside the cliffs just north of Western Vermillius Gap.
Be warned that this is a higher level zone, so if you are still fairly early in your journey, you will likely just want to shield up, loot and then make a hasty exit.
You can see this location within the orange circle on the left side of the map in the image below.
Within this location you will find 4-5 chests that you can loot that can contain Diamondine Dust. You should be able to pick up 5-10 Dust on a single trip there.
Pro Tip: Combine this trip with an Aluminum harvesting/farming run because the cliffs and entrances to the Eastern Shield Wall just east of this location are teeming with Aluminum Ore.
Buying It From A Vendor
Given how easy it is to gather a decent amount of Diamondine Dust from Mysa Tarill, I hesitate to recommend buying it from the vendor, however it is an option.
In each of the two major commercial/social hubs (Arrakeen and Harko Village) you can buy the Diamondine Dust from the Weapons Vendor for 3,500 Solari.
This will require you to be at a Reputation Level of 4 with either faction however, as shown in the image above, so keep that in mind.
