Gemspark

Gemspark brings vanilla-style gems into the world and crafting system. Ores generate in the overworld, while the Pink Sapphire generates in the Nether through a datapack-style setup modeled on vanilla. The gems are tiered between iron and diamond, so each one sits at a point in the progression. Gem glass blocks resist explosions at about half the strength of obsidian, with diamond equal and ruby slightly weaker, and light-emitting variants of the blocks are included.

The mod also adds decoration blocks such as lamp posts with caps that let lanterns hang from an arm, fences that stick out from the block they are placed against when sneaking, and two pedestals alongside sixteen colored redstone lamps. Wearable cosmetics and some equipment are added for players who want them. Those cosmetics need Curios API installed, which is an optional dependency. Athena is a required dependency and must be installed alongside Gemspark. Connected textures are available with ConnectedTexturesMod if a player wants them.

Gemspark runs on Forge and NeoForge with the client and server environment, so both the server and every player need it. Files cover game versions 1.18.2, 1.19.2 and 1.20.1, and the latest file is 1.3.11 for 1.20.1. The mod is released under All rights reserved and is not open source, though its source code and issue tracker have public links.
