Despite its excellent structure, ChatGPT is somewhat useless for gemstone information. Allow me to explain why.
People mistake ChatGPT for an intelligent AI that thinks for us. In fact, it is simply a sophisticated algorithm that selects the appropriate section of text in its answer as the one that makes the most sense compared to the enormous database on which it has been trained.
And now for the first problem: The internet (and most likely the database it's been trained on) contains practically no information about gemstones. Only a few well-known laboratories and newspapers share exciting news with the public, while the rest of the material is either fact that has been shared millions of times (such as ruby and red spinel) or misleading information.
As far as I know, this AI was trained using a database containing only these few elements.
Most true secrets are guarded by gemologists and are only shared from ear to ear. What you see online is a tiny part of the real gemstone world.
GIA, GRS, and other companies give valuable information. Yet, if you want to access most of their information, you must pay a monthly membership fee, lowering actual knowledge about gemstones to the public.
