When I was getting ready for my wedding last month, one of the obvious things we had to do to get ready was to pick out wedding rings. I'm not much of a jewelry wearer myself, but I put a lot of thought into this choice, and in the end, I learned quite a bit more than I knew before about the jewelry profession and how it works. It struck me as a profession for people who really love making beautiful things and who love interacting with people at some of the most significant moments of their lives (such as ... weddings) -- but above all, real life jewelcrafters struck me as people who love details.
Of course, a number of professions in Azeroth have to pay attention to details in their various gaming aspects. Deciding which items to make for oneself, which to sell at the auction house, and how to use your chosen profession in itself requires lots of details. But when you think about roleplaying, there's a definite difference between blacksmithing on the one side, with its broad strokes of a hammer on metal, and jewelcrafting on the other, focused on the smallest of cuts and adjustments that the naked eye can't even perceive. Jewelcrafting is the profession on Azeroth that requires the keenest eye, the steadiest hand, and the most attention to detail.
In some ways, jewelcrafting in the real world seemed like sub-world of its own, where jewelers knew special secrets no one else knew. They used these secrets to draw forth items that were at once dazzling and magical, artistic and personal for each individual that wore them. Jewelcrafters in the World of Warcraft have no reason to be less devoted to their profession, or any less proud of their ability to craft the most delicate of magical items with the most powerful magical effects, using the secret knowledge only they can understand.
