I went with L'Excellence Diamond, I found their prices to be significantly lower than other retailers, by as much as 20%-40%. Their showroom is located at Singapore Land Tower in Raffles Place, and it's by appointment. It's a family company, very knowledgeable, and the quality of their diamonds and craftsmanship is impressive for the price. I like that I could customise everything from ring design, prong shapes to engraving. Very happy about the ring and really good overall experience.
