<prompt> Human: I dont think Im posting this in the appropriate forum but I wasnt sure where else to go.Ive heard you should purchase a ring equivalent to 2-3 months of your salary. Is this common?Im not ready to purchase but I am ready to start looking into it.Thoughts?Edit: Great advice everyone! After reading your responses, I definitely want to do some research on other gemstones. Ill probably discuss ring types with her and see if shed be interested in something other than a diamond but just as nice. If you have some knowledge on gemstones-- drop it!! Thanks!  <response>: Ive heard you should purchase a ring equivalent to 2-3 months of your salary.Thats what the people in the industry want you to spend because it makes them more money.Buy something you can afford in cash that is nice but fits into your overall financial picture.
