Tag implication: crystal_earrings -> earrings

Posted under Tags

I probably should have written that it was made out of a gemstone or a gem instead of crystal, but I was sticking to the tag being called crystal earrings in spite of the misnomer. If the earrings are made out of gems, wouldn't it be just as sensible to call them gemstone earrings, gem earrings or something equivalent?

As for diamonds, I was referring to the shape, not the gemstone.

Speaking of crystal, I have some serious misgivings about that wiki. Even though it's scientifically accurate in its description, it does nothing to clarify how the tag is actually used in practice, that is, big shiny rocks and Flandre's wings.

As it is now, one could tag any given crystalline solid (sugar cubes, for instance) as "crystal" and be technically correct.

Not a fan of using that definition for crystal either. If there's going to be a crystal tag, I'd personally think it best kept to what people would commonly think of as crystaline shapes like post #2233721, post #2181324, or post #2145492. Or Flandre's wing hangers. Then if it's substance is readily apparent, add a tag for that like ice, salt, or gem. Only trouble there is defining the shapes people are looking for.

As far as the original implication though, not sure; We don't have a tag for rings set with gemstones either to go off of, and all of the populated tags for more specific rings describe purpose/location rather than substance or shape (ie tail ring, wedding ring, toe ring, etc) . Makes me wonder if we even need an implication for either; Just continuing to tag gem and ring/earring seperately could certainly work.

How about this for crystal and gem.

  • Crystal: An object composed of translucent material and whose surface is composed of facets (flat sides).
  • Gem: A polished or cut precious stone, commonly used in jewelry.

Crystal covers both raw crystals (disorganized facets) and cut (organized facets).
Gem covers polished (no facets) and cut precious stones and crystals.

Some other definitions

  • Diamond: White/clear crystals
    • Restricting Diamond to having to have facets of some sort.
  • Ruby: Red colored gem and crystals
  • Sapphire: Blue colored gem and crystals.
  • Emerald: Green colored gem and crystals.
  • Amethyst: Purple colored gem and crystals.
  • Topaz: Yellow and Orange colored gem and crystals.

My only question is on Diamond; The other gems are largely defined by their colors, but a lot of diamonds aren't white/clear. In fact, there are large numbers of famous diamonds with deep colors (https://en.m.wikipedia.org/wiki/List_of_diamonds).

Not that we couldn't just use it for clear/white gems anyways since "pure" diamonds are that way.

Normally they are colorless since they break visible light.
What you're talking about is impureness (may be nitrogen (-> yellow) or other substances).
But we treat here images and therefore the ideal picture of an diamon should be applied and this is colorless.

I know.

Just saying it's kinda weird we wouldn't tag some famous diamonds as diamond due to impurities.

Though I actually wonder just how important tagging gems by type/color is in the scheme of searches and such.

Well, we have a ruby_(stone) tag but the one who added this tag was me. Same thing for sapphire. So I don't really think this is that important if it's only used by one user xD.
