Regardless of your price point, you will have a wide selection of styles to pick from, each almost as unique as a snowflake. That brings a lot of pressure when you are out shopping for a ring. Following are a few things you should not do.     Get Caught Up The crowd is not the most intelligent source of inspiration at the best of times, which means following trends will not guarantee that you will get the best value. What you should focus on is the suitability of the ring to personal taste, because a diamond ring is not something one buys often. Fixate on Size The number of carats should not be the only deciding factor when picking out a ring. There are other things to consider as well, such as cut, color, and clarity. Ignore the Setting The setting used on a ring can make a huge difference. If you cannot decide, ask for opinions from friends.
