Regarding which brand of diamond ring to buy, I don't think anyone can give you an accurate answer, because everyone likes different brands, so if you want to buy a proposal diamond ring, you should choose a custom-made one from a jewelry store that you are familiar with or your girlfriend likes according to your personal budget. Actually, it's not the most important brand of diamond ring you use to propose. The most important thing is that when you propose, you must let your girlfriend know how much you love her, and you should give her a lifetime commitment like the meaning of CTloves' true love ring (only love jewelry, men can only buy one with their ID cards all their lives), so that she can believe that you can make her happy all her life and can safely deliver herself to you.
