Celtic engagement or promise ring, this ring could be used in either situation just be clear which it means! I have sold so many of this specific ring to be worn as an actual engagement ring/set it is really unusual and pretty it is the celtic style of a traditional wedding ring and then you do not need another ring.
You will also find many really pretty high class CZ engagement rings, to wear in the meantime while the real ring gets on your hand or wether you want to just wear it to ward off unwanted attention where there are smarmy guys, on a bar stool just, lurking around. Once people spot a ring on your left hand usually they will leave you alone.
Whether you're trying to dodge cheating creepy guys at the bar, you are a lesbian and do not feel the need to explain, if going to a business convention where cheating is the norm, you are a waitress or bartender in a bar, going to an ex's wedding, your high school reunion, just slip on your CZ engagement ring and then act as if you are engaged. I wear mine whenever I am in Las Vegas, they leave me alone every time.
