Hi there! Currently, we have allow DEAR and SIGN to top-up for diamonds other than LOVE. LOVE and DEAR have the same exact rules, topping up of minimum 10 diamonds in a single bill and get 1000 diamonds while SIGN will get complimentary of 10% per top-up. There is also fiat top-up where you can get double diamonds on your first top-up. The more you top-up, the more discount you get and the more enjoyment you experience!
