This near eternity band (they note the unadorned gold at the back is to keep it stable and more wearable) by Devereux would be a great left or right hand ring.

They explain, “This eternity band just oozes romance. Thirteen bright reclaimed diamonds, totaling just over 1 carat in weight, are nestled into recycled 14k yellow gold cups, and are framed with a delicate milgrain (those are the sweet little bumps you see surrounding the stones). Our favorite part about milgrain is what happens to it over time – the way hand-holding and comfort-twirling slowly softens it. Spend a few decades loving in this sweet band, and you can see for yourself.”

This is priced at USD$2,400.
