Or new, anyway. Tam posted links to her first but Julie is a welcome addition to the gunblogosphere, especially since she hails from where it's summer when we're shivering in snow. Along about January, I'll be hoping for reports of sunshine from Perth. Um, okay, begging.
And via her, a link to some RJ-45 based interestingly-geeky jewelry at Artful Articulations. I think one could do more a delicate version (in size, anyway) with male and female SMA connectors, typically gold-plated and about 1/4" OD; they'd need to be pared down to the minimum for jewelry but that's exactly the kind already made for direct circuit-board interface.
For a more Victorian take, 7mm connectors would be ideal, but they'd have to be lockets: as UHF-and-up connectors go, they're huge. But they refrain from doing anything so coarse as actual mating: when they hook up, they chastely kiss. Downside: these high-precision connectors cost like jewelry already! Very cool but a little creepy. (Creepier still when you look at 'em with test equipment: on the frequencies where I play, they do. not. show. up. There's no discontinuity at the interface as far as the costs-more-than-a-Tesla-roadster test gear can see. They're stealth connectors!)
