Here's a better explanation of how to get a lot of diamonds but first there are two kinds of currencies: diamonds and rubies. Diamonds are the one you're looking for to get.
1a) Buy diamonds (the least amount like 2$ or 5$, depending on which one you see. I saw the 5$.)
1b) keep playing until you have enough diamonds for the cheapest item. Don't know how long it takes but if you don't have any purchasing info or like to not waste money, this is your only option.
2) Buy the cheapest item WITH diamonds located in the Inventory. Scroll down till you see them.
3) Buy them once, restart the game, and you will be filled with lots of diamonds, not gems but you can easily buy them.
A VERY BIG NOTE: DO NOT BUY THOSE ITEMS MORE THAN ONCE (ANY OTHER ITEMS THAT REQUIRE RUBIES ARE FINE). YOU WILL BREAK YOUR GAME AND THEREFORE HAVE TO CREATE ANOTHER ACCOUNT. THERE IS NO CHANCE OF DELETING YOUR GAME DATA. IT SAYS SO RIGHT HERE IN THE NUTAKU FAQS SO ONCE YOU FUCK UP, YOU FUCKED UP. Unless you're willing to wait like, I don't know, a year or so.
