Does anyone know when the possibility of building the sixth Gem Mine appears?

It's because I'm level 129, Castle lvl 9, and I have 4 Gem Storehouses and 5 Gem Mines (the game does not allow me to build more), also by raising Castle level to 10 and 12 gives you the ability to build 1 more Gem Mine and Storehouse.

So in total I will have 6 Gem Storehouses and 7 Gem Mines, missing 1 Gem Mine
