Because your future is valuable, only the best will do. Your fiancée will know you care for her if you give her an 18k white gold engagement ring with a princess-cut diamond. That's not all, though. Every time your princess glances at the 0.75 carat E/VS graded diamond, she will be delighted. The diamond is put in a claw setting because this maximises the sparkle and brilliance of the diamond. Why would you choose anything less when there are all these advantages?
