Aquamarine Ore, Blocks, and Equipment Upgrades
Aquamarine is an ocean-aligned upgrade tier in Mythic Upgrades used to craft high-durability armor, weapons, and aquatic crystal architectural blocks.
Sourcing Aquamarine
Aquamarine originates from underwater mineral deposits and deep stone veins:
Aquamarine Ore: Generates in stone strata and submerged underwater ocean floors.
Deepslate Aquamarine Ore: Found deep within subterranean deepslate layers below Y=0.- Aquamarine Gem: The raw gemstone dropped upon mining or smelted from ores in a blast furnace.
- Aquamarine Crystal Shards: Mineral fragments used in crystalline masonry and decorative stonecutting.
Mining Aquamarine requires an Iron Pickaxe or better. Mining with a Fortune-enchanted pickaxe increases the number of gems dropped per block. In version 1.20.1, players can place raw Aquamarine Ore or Deepslate Aquamarine Ore into a blast furnace to quickly produce pure 
Aquamarine gems.
Forging Aquamarine Ingots
To forge tools and armor, raw gems must first be alloyed into metal ingots:
- Combine 4 Aquamarine gems and 4 Necoium Ingots in a crafting table (shapeless) to produce 1
Aquamarine Ingot. - 9 Aquamarine Ingots arranged in a 3x3 grid form 1
Block of Aquamarine, which can be uncrafted back into 9 ingots.
Smithing Aquamarine Equipment
Upgrading tools and armor to the Aquamarine tier is performed at a Smithing Table using the Mythic Upgrade Smithing Template:
Smithing Template + Netherite Sword + Aquamarine Ingot -> 
Aquamarine Sword- Smithing Template + Netherite Pickaxe + Aquamarine Ingot ->
Aquamarine Pickaxe - Smithing Template + Netherite Axe + Aquamarine Ingot ->
Aquamarine Axe - Smithing Template + Netherite Shovel + Aquamarine Ingot ->
Aquamarine Shovel - Smithing Template + Netherite Hoe + Aquamarine Ingot ->
Aquamarine Hoe - Smithing Template + Netherite Helmet + Aquamarine Ingot ->
Aquamarine Helmet - Smithing Template + Netherite Chestplate + Aquamarine Ingot ->
Aquamarine Chestplate - Smithing Template + Netherite Leggings + Aquamarine Ingot ->
Aquamarine Leggings - Smithing Template + Netherite Boots + Aquamarine Ingot ->
Aquamarine Boots
Additionally, existing gear from alternative gem tiers (such as Citrine, Jade, or Peridot) can be transformed directly into Aquamarine gear using the same template and ingot.
Crystalline and Schist Architecture
Aquamarine provides an extensive decorative masonry catalog:
- 4 Aquamarine Crystal Shards (2x2) -> 1
Block of Aquamarine Crystal - 4 Block of Aquamarine Crystal (2x2) -> 4
Polished Aquamarine Crystal Block - 4 Polished Aquamarine Crystal Block (2x2) -> 4
Aquamarine Crystal Bricks - 1 Cobblestone + 1
Aquamarine Crystal Shard -> 1 
Aquamarine Schist - 4 Aquamarine Schist (2x2) -> 4

These blocks can be processed on a Stonecutter or crafting table into stairs, slabs, walls, and pillars.
