Deepslate Coal Ore
Deepslate Coal Ore is the deep-cave variant of coal — same drops, harder rock, distinct dark texture introduced in 1.18.

Description
Deepslate Coal Ore was added in the Caves & Cliffs Update (1.18) when Mojang restructured the Overworld's underground. Below y=0, regular stone gives way to deepslate — a darker, harder rock — and every ore that previously generated in this zone gained a deepslate variant. The coal version sits in a moody dark-grey matrix studded with the same black coal flecks, making it instantly readable on cave walls.
Functionally, the block is identical to its surface cousin: a wooden pickaxe drops one piece of coal, Fortune adds bonus rolls, and Silk Touch returns the ore intact. The only meaningful difference is mining speed — deepslate is significantly tougher, so even with a stone pickaxe each block takes noticeably longer to break. Players using haste beacons or efficiency-enchanted iron pickaxes barely notice; new survivors definitely do.
