I recommend Power Jewellry on 19A Hankow Rd, TST. They were recommended to us by friends of my parents and they have an excellent reputation for price and being genuine. They recoated my wedding and engagement rings at a very good price, after I had bashed them around a bit with wear and tear. As a female, I would personally would go for cut and clarity over size when choosing an engagement ring. My husband and I visited my family jeweller who was also a long time family friend ( since deceased sadly) . When asked, he said that he knew exactly what would suit me, and he was spot on. Of course, my mother was like, " he doesn't love you if he won't buy you at least a carat!" Utter Crap. A carat in size looked too big as I have small hands but the cut and clarity were perfect and a well balanced .58 carat. A ring should be about showing quality of your commitment not how much you can afford. Different cuts and sizes suit different women.
