BackPack and Gems
BackPack and Gems adds a backpack upgrade path, gem-based tools and weapons, and a gem-producing machine for NeoForge 1.21.8 – 1.21.11.
What it does
The mod centers on the player's inventory and equipment. A standard Backpack can be crafted and then upgraded into a Reinforced Backpack, which holds more items for longer expeditions. The reinforced version is made from Reinforced Leather, so the upgrade depends on gathering that material first.
Gems are the base of a progression system. Empty Gems are introduced early, and a new machine block turns them into the gem material used for new tools and equipment. The set includes a sword for fighting enemies and a Gem Pickaxe with higher durability and speed that mines a 3x3 area. Jewelry and a new Music Disc for the jukebox round out the additions, and custom achievements guide players through the content.
The mod is built for NeoForge. Its release line covers 1.21.8 – 1.21.11, and the latest file is 1.0.0 for 1.21.11, published 2026-01-11. It must be installed on both the client and the server, and it is released under All rights reserved, so it is not open source.

How it compares
Goulden's Vanilla Backpack is NeoForge, built for 1.21.1, under the MIT License and open source, so it adds backpacks without gem tools or a progression system. Create Backpack Upgrades is also NeoForge for 1.21.1 under the MIT License, and it is not open source, with upgrades aimed at the backpack rather than gem gear. Iron's Gems 'n Jewelry is NeoForge for 1.21.1 – 26.1.2 under All rights reserved, so its version range reaches further, but it is not open source.
