Does blue work as well as gold or silver for everyday wear? Yes, and it actually mixes better than people expect, because a proper blue reads as a neutral the same way navy does in clothes. It sits against denim, against white, against black, without ever looking like it's trying to match anything, which is the whole point of a colour you wear often.
If you've got none, start with something in a mid toned blue rather than the palest or the darkest version, because that middle shade is the one that works with the most skin tones and the most outfits. A thin bangle or a simple beaded stretch bracelet in that tone is the easiest first buy, something you can put on without thinking and take off without it leaving a mark on your wrist. Save the bright cobalt or the near black navy for later, once you know whether you reach for blue at all.
The difference between a good one and a disappointing one shows up fast, usually within a week. A well made bracelet has a clasp that opens and shuts properly without pinching the skin on the inside of your wrist, and any stones or beads are set so they don't rattle loose after normal wear, not just a shake test in the shop. Plating on the hardware should feel slightly heavy rather than hollow, and the colour itself should be consistent all the way round rather than paler on one side where the dye or enamel has thinned. Cheap ones tend to show their age at the clasp first, it goes stiff, then loose, then it just stops closing properly, often within a month if you wear it daily.
Before you buy, check the bracelet actually sits where you want it to sit on your wrist, not riding up over the wrist bone where it'll catch on sleeves, and not so loose it spins round and shows the plain backing of the beads or stones rather than the coloured front. Try it on with your coat sleeve, not just bare arm under a shop light, because that's where most bracelets actually get worn. If it has a chain extender, check the smallest and largest settings both feel secure, not just the middle one the assistant hands you. And look closely at how the blue element is attached, glued in beads can pop out, but bezel set or properly threaded ones won't.
Over time the better ones mellow rather than fade. The metal takes on a slightly duller, warmer finish that looks lived in rather than tarnished, and the blue itself, if it's enamel or good quality glass, barely shifts at all. The ones to worry about are the painted finishes, which chip at the edges first, usually where the bracelet knocks against a desk or a steering wheel, and once that starts there's no fixing it, only replacing it.
