Diamond Ore block texture Deepslate Diamond Ore block texture Diamond Below Y:16, more common the deeper you go, also found in Fossils if below Y:0 Needed to craft the two best sets of tools and armor in the game, but doesn"t have many other uses.
Redstone Ore block texture Deepslate Redstone Ore block texture Redstone Below Y:15, more common the deeper you go below Y:-32 Used to build redstone circuitry, which is useful for automatic farms and contraptions.

Emerald Ore block texture Deepslate Emerald Ore block texture Emerald Above Y:-16, most common high up at Y:232 (only found below mountains and Windswept Hills) Used as a currency for trading with Villagers. Otherwise almost useless.
Magma block texture Magma Block Underwater, below Ruined Portal, the Nether When placed below water, this block produces a column of bubbles that sucks anything above it downward.
It deals fire damage to any mob or player standing on top, and if ignited, the fire never burns itself out.
Obsidian block texture Obsidian Water and Lava interactions, Ruined Portals Obsidian takes a long time to mine, even with the proper tools, and is blast resistant.
Besides building, it is also used to craft Ender Chests and Enchanting Tables, and for the frame of Nether Portals.
Glow Lichen item texture Glow Lichen Caves and open spaces Glow Lichen is an alternative light source that is dim like a redstone torch. Unlike torches, it can be placed on ceilings.
Amethyst block texture Amethyst Cluster item texture Amethyst Amethyst Geodes The block can be used for decoration, or in the construction of Sculk Sensor networks. Amethyst Shards are used as a crafting ingredient.
Calcite block texture Calcite Amethyst Geodes Yet another decorative Stone variant with no other uses. Calcite is easier to mine than other forms of stone.
Smooth Basalt block texture Smooth Basalt Amethyst Geodes and Ancient Cities Basalt is a decorative Stone variant typically found in the Nether. Smooth Basalt can"t be crafted back into regular or Polished Basalt.
Dripstone block texture Pointed Dripstone item texture Dripstone Dripstone Caves Pointed Dripstone is used in lava farms, and can drain Mud to make Clay. It also increases fall damage when landed on, and deals heavy damage when it falls itself, making it effective as a defensive weapon.
Clay block texture Clay Lush Caves Cooked to make Bricks (not to be confused with Mud Bricks) and Terracotta, two decorative blocks. Bricks can also be crafted into pots.
Moss block texture Moss Lush Caves When bone meal is used on it, it replaces nearby dirt and stone with more Moss. It also produces tall grass and Azaleas. Moss can be mined very quickly with a hoe, more quickly than Stone with a pickaxe, making this the quickest way of removing Deepslate without explosions.
Moss can also be composted to get more Bone Meal. In fact, optimally growing Moss and composting it produces more Bone Meal than was used to grow the Moss in the first place.
Oak Planks block texture Oak Log block texture Dark Oak Planks block texture Wood Abandoned Mineshafts, or farmed from Azalea trees One of the three most used crafting materials. Wood is especially important, since the crafting table and all tools' handles are made from it. Logs can be smelted for charcoal (a coal substitute), which other forms of wood can't. Oak wood is obtained from Azalea trees, Abandoned Mineshafts, and Strongholds, whereas Dark Oak wood is obtained from Mesa Mineshafts and Ancient Cities.
Vine item texture Vine Lush Caves and Jungle Vines can be climbed by holding the jump button, or if against a wall, by walking into the wall. Compared to other types of vines, regular Vines naturally grow indefinitely downward, spread horizontally, can"t be bone mealed, and are placed on the side of blocks instead of the top or bottom.
Cave Vines block texture Glow Berry item texture Glow Berries Lush Caves When placed on the underside of a block, they form Cave Vines that can be climbed like normal Vines. Using Bone Meal does not cause them to grow downward; instead, it causes the block bone mealed to grow edible Glow Berries that produce light and can be harvested with right click.
Compared to other types of vines, Cave Vines can be placed only on certain types of blocks, will only grow so far down naturally, and aren't grown downward by Bone Meal, making the other types of vines better for infrastructure purposes.
Sculk block texture Sculk Deep Dark Can be mined for EXP, or harvested with Silk Touch. Sculk Sensors can be used for wireless redstone and Sculk Catalysts for farming more Sculk, but natural Sculk Shriekers are a major hazard and should be avoided.
Bedrock block texture Bedrock Bottom of the world Bedrock is an unminable, blastproof block that generates at the absolute bottom of the world. It can only be removed using glitches in the game, and there is nothing below it but an endless void.

Terracotta block texture Terracotta Trail Ruins, Near surface: Mesa (Badlands) Dyeable decorative block. Dyed Terracotta can be smelted into Glazed Terracotta, another decorative block which has a niche use with redstone since it can be pushed but not pulled by pistons.
