Stardust Crystals can be mined from Miners using the Stardust Crystal Potion. A chisel is required to open the crystal for a small amount of stardust. The larger the size of the crystal, the more stardust it gives. Gemming the chisel gives 5% more stardust with each tier, for a maximum of 20% at Diamond. The Blue Chisel Orb gives an additional 10% more.
Below is the Stardust Crystal stats table. At 75 mining or above, one can gain about 52,000 stardust per day without the 30% bonus. With the bonus, it would be 69,333, which is the equivalent of approximate 10 Stardust Potions (includig the 15% longer duration from the achievement perk).
