I'm so sorry to have to tell you this, but you've made the item in the wrong quality. The writ is asking for Superior quality and you made Legendary quality.
Any chance of helping this person out? This is, sadly, a mistake I have seen more than one beginner make. The game does an iffy job of explaining the adjective/color relationship (i.e., "fine" = green, "superior" = blue, etc.). I hate to see someone spend 2,000,000g on a writ that probably should have cost less than 50,000g. Maybe remove the crafted gold ring from their inventory and give them back the platings and dawn-prism?
