Amethyst Expansion
Amethyst Expansion brings new amethyst blocks, including amethyst brick variants, to Fabric worlds on the 1.21 line.
What it does
The mod stays close to vanilla: it extends the amethyst material with new blocks, such as amethyst bricks, stairs, slabs, walls, fences and fence gates, and adds recipes that craft them from existing amethyst items. Both the server and each player need it, since the blocks must exist on both sides. Builds cover 1.21 – 1.21.11 on Fabric, released under the MIT License but not open source.
Key features
Amethyst brick blocks
New amethyst brick blocks join the decoration options, giving builders a brick-style material in the amethyst family.
Stairs, slabs, walls and fences
Matching stairs, slabs, walls, fences and fence gates are added alongside the new amethyst bricks.
Crafting recipes
New recipes turn amethyst materials into the added blocks, using standard crafting so the content fits the vanilla progression.
