It's absolutely not 10x. It's probably closer to 2x, a rate that was never even used on DMM.

And because Jewels are so completely worthless for Rate Ups in Nutaku, it doesn't really matter when you spend them. The chances of getting a Rate Up is astronomically low. You want to use them now? Go ahead, you won't get the Rate Ups. You want to use them later? Go ahead, you won't get the Rate Up Hime.
