Hmm... I thought I had tested before that the Flint came in addition to the Gravel, and thusly that the Flint was renewable, even though the Gravel is non-renewable (albeit it is one of the Blocks I don't really count as non-renewable as it is found in such great quantities).

But, I now dug through a stack of Gravel, twice, and I'm left with 53 Gravel and 11 Flint. So it is indeed non-renewable, and I wrongly undid your edit. I'll fix it.

Regarding the trading part, then the Fletcher Villager will accept 10 Gravel and give you 1 Emerald, and it'll give you 6-10 Flint for 1 Emerald. So the quantity will diminish here as well.
