If you've ever admired someone's engagement ring, you've probably oohed and aahed over the size or shine of "the rock," as many like to call it.The diamond or other gem in an engagement ring is a key element, but it's important to remember the entire ring needs to be durable since it's typically worn every day.Unfortunately, some of the most popular engagement ring styles throw practicality out the window in favor of aesthetics.Business Insider spoke with private jeweler Anna P. Jay, who is based in Nantucket, Massachusetts, and Charleston, South Carolina, about engagement ring styles that may not stand the test of time.Thin bands aren't that durableCelebrities like Taylor Swift and Zendaya have been favoring chunkier engagement rings in recent years, but rings with very thin bands are still popular in the market. Jay said the latter can be a mistake."I don't like super-thin bands personally because sometimes they're not sturdy," Jay said.Though thin bands create a sleek look and can make a stone appear larger, they aren't as supportive, particularly if your ring has a large carat stone.
