Thanks for your reply. The second one that you qoute sounds fit my budget. But how come colour D can fit into this price range($50K), I got qoute from other company, they can give me colour F or G only with this budget.
Another question, the diamond is for my wife, so for clarity SI1, is it good enough? 會唔會用肉眼睇都好礙眼? What about VS2? Thank you
