Diamond Duplication
Diamond Duplication lets a player turn carbon ore and a diamond into extra diamonds through a crafting table, as a Forge economy mod for 1.20.1.
What it does
Carbon Ore combined with one diamond at a diamond crafting table yields two diamonds, so the mod works as a duplication route for diamonds in survival and on servers. Servers that run it need every player to install it too. Only a single build exists, 0.1.0 for 1.20.1, released under the Creative Commons Attribution Share Alike 4.0 license; the mod is not open source.
Key features
Diamond crafting recipe
A crafting table recipe turns one diamond and carbon ore into two diamonds.
Granite and andesite conversion
Granite and andesite are replaced in the recipe chain, making diamonds easier to reach on servers.
Ore-based economy
Diamonds gained through the recipe feed the economy of a server, where the rate of diamond supply matters.

What the author says
This Mod adds a "Carbon Ore" to the game and it allows you to duplicate diamonds using 2 carbon and 1 diamond and it has a chance to replace granite and andesite and it is a useful mod for servers to get diamonds a bit easier but you need to get a diamond pick to mine the ore.
