hi i want to ask something, i'm an android user, i want to buy diamonds but i don't have credit card, so i decided to buy google gift card instead,and here's the question: can we buy diamonds from US region gift card (since the currency displayed when i tried to purchase it was already changed to dollars, but i'm not really sure it'll work)? or should we buy Japan region gift card?
