<prompt> Human: Hi Reddit!Throwaway because my girlfriend browses Reddit.Please dont recommend moissanite or other non-diamond stones, because my girlfriend is not into those.So last NYE my girlfriend said that her goal was to be engaged by the end of the year shes pretty blunt.... Throughout the year Ive been putting aside money for the inevitable ring purchase. We have a big trip coming up in a week and I want to use it to finally propose to her!Weve looked at a few jewelry shops nearby so I know the general style she likes. But I have no clue what to spend.Background:Were both around 25, both debt-free, I make about 85k and she makes about 70k. Ive got around 34k sitting in my checking account I dont really spend all that much money on random things and I just got a five figure signing bonus and a healthy 401k. Im anticipating a 15 bonus next year. Her family is going to fund the bulk of our future low-key wedding.I want to purchase from Costco because I trust them more than a jewelry shop, and all their rings seem to be pretty high quality.So far Ive seen rings between 6.5k and 13.5k that Ive liked. I plan on buying on a credit card and immediately paying it off for that sweet cash back. Does this seem like a reasonable range for me to shop around in? 13k seems a bit excessive, so I imagine Ill settle in around 8k depending on what I find at Costco.TL;DR: What should I spend on an engagement ring?Bonus question: Anyone have experience going through airport security with a ring? :  <response>: Why do you trust costco more than a local jewelry shop? Pick a small local jeweler. I have a good relationship with my jeweler. I picked the ring they showed me multiple diamonds allowing me to select the one I wanted they then mounted it for me. They worked with my price range. I now have a very good relationship with them and they work with me.
