Here are a bunch of rocks that are aesthetically pleasing, I guess. The moment your partner slips this baby on your finger, you may begin to feel resentment that will last longer than your marriage, but love is about sacrifice, right? And you’re being a better person by giving up the diamond dream, so okay. These rocks at least resemble the diamond engagement ring of your dreams, unlike that dainty twisty ring that looks like a couple pieces of thread got caught in your fingers. Diamonds are forever, but rocks last a while too.
