Deepslate Diamond Ore generates between y=−64 and y=16, with the highest concentration around y=−59 — well within the tightest, deepest part of the cave layer. Since the Caves & Cliffs Update (1.18), almost every diamond a Survival player ever finds comes from this variant. The texture is the most coveted in the game: dark grey deepslate cradling clusters of bright cyan crystals that almost glow against the surrounding stone.

An iron pickaxe is the minimum required tool — anything weaker drops nothing. Mining yields one diamond, with bonus rolls under Fortune III pushing the average above two. Diamonds craft into pickaxes, swords, axes, shovels, hoes, full armour sets, jukeboxes, music discs, enchanting tables, firework stars, and the components needed to upgrade gear to netherite — the only path to the strongest tier in the game. Silk Touch returns the ore intact, which experienced players sometimes prefer to maximize Fortune potential at a later point.
