LAPIS LAZULI

Lapis Lazuli is something you buy from villagers rather than sell to them; it does not appear as a raw-material trade, so trading is one of the few survival-friendly ways to stock up on it.

Lapis Lazuli is a utility or magical item tied to the Cleric's brewing-stand economy, and trading is a dependable way to keep it in stock. No recipe in Java 26.2 produces it, unless you count unpacking a block of lapis lazuli: it comes out of deepslate lapis ore and lapis ore. One lapis lazuli on a crafting grid becomes one blue dye.

To buy Lapis Lazuli, visit a Cleric at the Apprentice tier (1 emerald).

Lapis Lazuli sells for as little as 1 emerald, from the Cleric at the Apprentice tier, and nothing else on the list costs less. The price is fixed rather than rolled, so a second Cleric will quote you exactly the same.

The Cleric at its apprentice tier asks 1 emerald for lapis lazuli. 8 of the 72 villagers that pay emeralds, emptied out:

a dark oak boat against 32 sticks for the same 1 emerald, 32 times the carrying, and the shortest wait is the Leatherworker at 37.5 real seconds of shelf, gathering not counted.

Every lapis lazuli offer here locks after 12 uses, and a villager restocks up to twice per Minecraft day, so one is good for 24 of these trades a day and no more.

The earliest lapis lazuli shows up is the Cleric's Apprentice tier, level 2 of five, which a villager reaches at 10 trade experience. A freshly employed one is 1 tier short of offering lapis lazuli at all.

12 lapis lazuli empty one slot at the Cleric, 2400 ticks (Villager.allowedToRestock) at 20 a second (TickRateManager) refill it 2 real minutes later, and the 24000-tick villager day (Timelines) holds 2 of those fills in 20 real minutes.

So one cleric moves 24 lapis lazuli against 24 emeralds a Minecraft day, lapis lazuli every 50 real seconds, 1.2 emeralds a real minute. 64 lapis lazuli take 6 fills across 3 Minecraft days, 6 minutes of it watching the cleric walk back to its brewing stand.
