Memory rings (also known as "midi rings" and "first knuckle rings") are one of my absolute favorite accessories - I wear them every single day of my life, no matter how casual or fancy I'm being, and love how they're simultaneously elegant and a little edgy. They were super-trendy for awhile, but at this point I think they've transcended being a "thing" and have become just another category of accessory - meaning that while you can find them for next-to-nothing, they're not necessarily a bad place to lay out a little extra money for a piece you'll have forever.
To me, memory rings (which are called that because you can use them to remember to-dos, transferring them from one hand to another when the task has been completed) fall into three basic price categories (I'm ignoring the ones on the $200+ end of the spectrum, because while they're very pretty it's also not necessarily especially practical to spend that kind of money on a ring that honestly might fall off your finger at some point; I've had a lot of luck with mine and even sleep in my rings without them slipping off, but you never know).
