Planetary Gemology, also refered as Extraterrestrial Gemology, Astrogemology and Exogemology, is a branch of gemology responsible for the study of gemology on extraterrestrial planets and celestial bodies. Planetary Gemology also works together with Planetary Geography and Planetary Geology.

"Planetary Gemology is gonna be really important in the future for find gems and ores in extraterrestrial planets and worlds."

Political Gemology

The art of cutting, polishing, and setting political narratives so they sparkle just long enough to distract the electorate from their lack of substance. It’s the strategic deployment of shiny policy proposals—often as artificial as a cubic zirconia—to deflect attention from deeper, structural "inclusions" (like corruption or economic inequality). A skilled political gemologist knows exactly how to hold a rough, unpopular truth up to the light and rotate it until it catches the public eye as a glittering promise, even if it’s fundamentally just a lump of coal.

Example: "The mayor's new infrastructure plan is a masterclass in political gemology. He's managed to make a single repaired pothole look like the Hope Diamond of public works, and everyone's so dazzled they forgot he just raised their taxes to pay for it."

Economic Gemology

The brutally practical application of geology to personal finance, specifically the art of buying, selling, and occasionally panicking over rocks that rich people think will hold their value better than the dollar. It’s the study of the global market forces, supply manipulations, and hype-driven demand that turns colored stones into alternative investments. It involves knowing that while a diamond may be forever, its resale value is often only for a weekend. It’s the field for those who believe their retirement plan is best secured in a safety deposit box rather than a 401(k).

*Example: "Dave ignored the housing bubble and put his life savings into a sack of raw emeralds from a sketchy website, fully believing in the principles of economic gemology. He's now living in a van down by the river, trying to trade a 2-carat rock for a sandwich."*

Cognitive Gemology

The mental process by which a person polishes their own flawed memories and biased opinions until they shine like flawless facts in the jewelry box of their mind. It’s the psychological tendency to focus on the "brilliant cut" of a memory that supports one’s current worldview while completely ignoring the dull, cloudy, or contradictory facets of an event. When two people engage in a heated argument, they are essentially each holding up their own polished cognitive gemstone, insisting it's a perfect, objective reflection of reality.

Example: "In his mind, he was the hero of every story, a flawless diamond of charisma and wit. His friends, however, were well aware of the cognitive gemology at play, remembering the numerous times he'd been more of a dull, clumsy chunk of pyrite."
