Deepslate Lapis Lazuli Ore is a deepslate variant of lapis lazuli ore found in the lower layers of the Overworld. It must be mined with a stone pickaxe or higher; otherwise, it drops nothing. Without Silk Touch, it drops 4–9 lapis lazuli, with Fortune increasing the yield (up to 36 with Fortune III).
Deepslate Lapis Lazuli Ore is harder to mine than its regular counterpart due to its increased hardness. When smelted, it produces lapis lazuli. Placing it under a note block creates a 'bass drum' sound.
