Blocky
The Blocky modification introduces a new type of stone in Minecraft called crystallite, which generates in the world alongside other natural stones like diorite, andesite, and granite. This unique mineral forms its own deposits among existing rock types.
In addition to crystallite itself, the mod adds multiple block variants made from this material, providing builders and designers with additional creative possibilities for decorating their structures.

The mod creator is focused on developing and maintaining larger projects, so a Forge version is not planned in the near future. The developer has also stated that adaptation for version 1.20.X will not be implemented due to lack of sufficient time.
If you have any questions or suggestions for improving the modification, you can contact the developer directly via Discord under the name gitgilev.
