What to do with Stardust in OSRS?

You can use it to purchase things from Dusuri's Star Shop in the entrance to the Mining Guild in South Falador. 

You should purchase these items first:

1. Celestial Ring (Uncharged) - provides invisible +4 mining boost (2000 stardust)

2. Star fragment - used to recolor items from Prospectors Kit to gold (3000 stardust)

   
   

To convert your Stardust to GP, these are the best options:

1. Bag full of gems - (GP/Stardust= 73.95)

2. soft clay packs - (GP/stardust= 74.67)
