So none of that changes anything. Magic doesn't care about subjectivity in what mortals desire. Worth at least 1000 is the same as 1000 as far as the magic is concerned. It's not as if the magic will fail if you have 501gp of diamond dust present for those spells that require 500gp of diamond dust. The "at least" is assumed to be present.do you not see the difference between the price of something & the amount of that thing? Sooo.... If it IS already "a fixed amount of material for the spell, rather than anything to do with price." What is the unit or volume for so I can list them on a tradegoods/commodity style list tuned for the setting I happen to be running (ie reberron FR darksun Ravenloft etc)?.....
Before you say "aha! there are several that call for A [thing] worth...", are you claiming that all instances of that thing (ie agate/jacinth/black pearl/etc) ever formed or found in every setting happens to be valued at that price?
- specially marked sticks, bones, or similar tokens worth at least 25 gp)
- (gold dust worth 25+ GP, which the spell consumes)
- jacinth worth 1,000+ GP and one silver bar worth 100+ GP
- (an agate worth at least 1,000 gp,
- A diamond worth 50gp
- The powder of a crushed black pearl worth 500+gp
- a focus worth 100+ GP, either a jeweled horn for hearing or a glass eye for seeing)
- a diamond worth 1,000+ GP, which the spell consumes, and a sealable vessel worth 2,000+ GP
- a gem-encrusted statuette of yourself worth 1,500+ GP
- incense worth 25+ GP,
- (ruby dust worth 1,000+ GP
- a diamond worth 5,000+ GP
- powdered diamond worth 200+ GP
- Diamond dust worth 100+gp
- etc.
As for will those gems be worth the same in all settings. Yup! Again, the magic doesn't care about subjective pricing in various settings. It doesn't matter to the magic that the Dark Sun wizard is using a 50000 ceramic piece ruby that would be 5000gp in the Forgotten Realms and 25000 if it was Kim Kardashian's cuddling ruby. The magic just wants a gem grade ruby of a certain size. The subjective prices are not relevant.
The DMG gives those standard ruby sizes and values. Ruby is 5000gp and all gem grade rubies of that size are 5000gp for the purposes of things like magic. If the DM wants one half that size, it's 2500gp as far as the magic is concerned.
