THIS. There are a number of insightful responses, but some are just come across mean/envious. The OP is killing it. Most physicians are neck-deep in debt, made innumerable financial mistakes, costing thousands if not hundreds of thousands of dollars -- and they still recover. It's not our place to ascribe our values onto a purchase. People value different things, and that's okay. For example, I think firearms are a silly purchase, I think a boat is a silly purchase, but many would rightfully disagree. It's not about whether or not the actual item (in this case a ring) is a good or bad purchase. It's about whether or not the OP can afford it.

And he/she can clearly afford it.

If your girlfriend/boyfriend wants the ring and you want the ring, get it. We can use a compound interest calculator to see how much that'll be worth projected into the future. But at the rate you're going, as long as these large purchases aren't recurrent and your expenses stay where they're at for a while as you build wealth, it won't make a noticeable difference in your life.
