Zhen U.N.

See? I'm not only about the bold, modern rings. Once in a while, even I can let out a teensy sigh over something ornate and delicate, something pretty. And if it's pretty you want, there's plenty of it at Zhen U.N. (pronounced, apparently, "genuine"), website of St. Louis designer Jennifer Yuan (or "jenyuan" — get it?). Pictured here is her "Divine Blues" ring, 18k gold with tear-shaped apatites, US$755.
