Chipped gems need a use
atleast be able to sell them to the banker...
They didn't care about stuff like that when the game was in development, I don't see that changing now that they've stopped.
I will suggest there is a tool which can be purchased from Shop to upgrade the gem.
-The tool can be used for 100 times
-It can combine lower grade gems to a higher grade. e.g. 3 to 1
-Meanwhile, we can financially support the server.
