I was wondering if a "*bling* glow"/masked-halo overlay would work better for... well, either quality or value, whatever is thought important. Or Artefacts only? Only on isolated[1] representations, if it helps.
I know that other games give something like a brownish (bronze/basic), white/tint-of-blue (silver/good), yellowy (gold/excellent), tint-of-blue/white (platinum?/epic?)... whatever... "quality/tier" indicator, sometimes as an item-glow, sometimes as tile-border[2]. Those that don't just render the object (major areas of its wash) in that key colour, but of course that's reserved for actual material. It's not exactly subtle, and I forget if there's any other use of a Glow already demonstrated elsewhere for something else. We're not likely to get radioactive contamination needing visualising anytime soon, are we?
I do return to my original comment of what you did being beautiful. If those can be usefully used[3] I'd still be happy. (Though I also admit I saw nothing different between 0% and 25% damage of armour.)
[1] i.e. not worn, so standalone infographic definitely. In a stock/beneath-interrogative-cursor/tradescreen list (as applicable), too. Whether whilst on the terrain floor.. depends on compatibility with other effects.
[2] Perhaps another suggestion for the footnote-1 'standalone' representation?
[3] Other comments about decorations not being suitably decorative... well, if it was modification-quality thennin lieu of reliable "menacing spikes" at that scale, it'd reasonably fit. And coexist with a base-quality glow for indication, perhaps?
