Drop rate (for sealstones of a random color) in chapter 13 seems similar to the soul gem drop rate. Not really one per tap (or close to it), but definitely decent.

You can get multiple of a color. -glares at 3x blue sealstones-

I think the only difference so far (aside from drop rates) is that you need specific colors for a set rather than the previous get-six-identical-gems-and-you-are-done thing.
