Here is an idea and implementation for biome specific gem generation and large chaos clusters that are marked by chaos nodes. Additionally, glow rose types are confined to the biomes in which gems generate. They act as signifiers of the type of gems in the biome.

The distribution of gems in based on and compatible with Biomes O Plenty gems but can be simplified with Forge biome tags. The distribution is a bit arbitrary atm.

The included config file uses the CoFH World Generator in the CoFH core: https://mods.curse.com/mc-mods/minecraft/cofhcore . Install this mod and add the config file to .minecraft/config/cofh/world It is meant to replace current gem, node and flower generation so you need to turn those off or set to 0. The world gen provides a proof of concept. Use XRay or WorldStripper to check the result.

This is designed to encourage adventuring and provide a basis for lore.

If you like the idea then you could implement something similar in your world gen. It could be a selectable generator option.
