I had a buddy ask me and I honestly had no idea. I saw online and a lot of places were saying 2-4 months of your salary.... which seems crazy expensive to me. Id be all about getting something nice, but spending thousands and thousands of dollars on a ring seems crazy to me and a waste of money you could put towards a house or a bunch of other things.... hard to believe you couldn't get a nice ring for around $1500 or so...
