Block of Emerald — Minecraft block

Overview

Minecraft classifies Block of Emerald as a building block. A crafting table turns its ingredients into Block of Emerald. A hardness of 5 makes it slow going without the right tool.

Anything below an iron pickaxe breaks it without leaving a drop. It drops as the same block you mined. It stacks to 64.

You make it with Emerald. No recipe takes it as an ingredient.

How long it takes to break

Block of Emerald sits at hardness 5: 25 seconds per block with your fists, 0.85 with the correct netherite tool.

An iron tool takes 1.3 seconds and a diamond one 0.95, so the jump that actually matters for this block is the one to diamond.

The block still breaks with a weaker tool, but below iron it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.

The Efficiency formula is level² + 1 added to tool speed — at V that is about 3.4 times the unenchanted rate.

Properties

Block of Emerald has a blast resistance of 6, so a nearby explosion will usually destroy it. It blocks light completely and emits no light of its own. 64 fit in a slot — a full stack. The fastest tool for it is a pickaxe; any other kind of tool mines it no faster than a bare hand does, because the speed bonus only applies to the tool class the block is tagged for.
