Stardust

Stardust can be mined from a shooting star from the Distractions and Diversions minigame. Shooting stars randomly land anywhere on Runescape every 2 hours or so. You can help identify where it would land by using a Telescope in a Player-owned house. Once you have mined a crashed star to the middle whilst gathering stardust, you can exchange up to 200 stardust to the Star sprite once every day. If you exchange 200 stardust, you can be rewarded up to 50,000 Coins, 158 Cosmic runes, 58 Astral runes, 20 noted Gold ore and the chance to mine 2 ores from any rock at the same time for a 15 minute period.
