Certus Quartz Crystal

Certus Quartz Crystal is an item added by Applied Energistics 2. Certus Quartz Crystal can be obtained by mining Certus Quartz Ore. This item is used in the majority of crafting recipes in AE2, such as Energy Cells and Formation Cores. You can also combine 1 Certus Quartz Dust and 1 Sand to get a Certus Quartz Seed, which you can grow in water to obtain Pure Certus Quartz Crystals which can be a substitution for Certus Quartz Crystal in most cases.
