I find that some rings meant to span more than one finger, or to go substantially up the length of the finger can put gimmicky style over substance. But I like this version from Melanie Auld; its form is compact and has impact at the same time.

Details say it’s faceted jade and amethyst and “micro pave”, but no specs as to what the micro pave materials are. The ring itself is 18k gold plated and, at the time of writing, was on sale from USD $113 to $79. So my money is on crystal or cubic stones. If you are interested note that it’s only available in size 7.
