byg:ametrine_ore => byg:ametrine_gems (smithing upgrade for netherite armor)
byg:pendorite_ore => byg:pendorite_scraps (smithing upgrade for netherite tools)
byg:anthracite_ore => byg:anthracite ("nether coal"; cooks 12 items)
byg:lignite_ore => byg:lignite ("end coal"; cools 16 items)

Ametrine and Pendorite generate only in very specific subbiomes in low rarities; assume like TR iridium.
Anthracite and Lignite are far more common. (assume like vanilla coal)
BYG does not come with it's own dust variants for the ores, just the gems / scraps.

Byproduct suggestions:
ametrine: chrome
pendorite: pyrope / red garnet
anthracite: / (vanilla coal does not have a byproduct either)
lignite: / (vanilla coal does not have a byproduct either)
