Ramsey instead left Arsenal to join Nottingham Forest on loan.
“We did make the enquiry, but we didn’t get the call back,” said Jones in Wales on Sunday.
“Maybe the player decided he didn’t want to come back to Cardiff and we’ll find that out over the next few weeks when the press ask him.”
He added: “The difference [between Cardiff and Forest] is that he’ll go there for a month and get fit, then you lose him again when Arsenal want him back.
“We’re a little bit more advanced as a squad and a club to just take a player for a month. If we took a player like that it would have to be for the rest of the season.
“You don’t want to get yourself into a position where you lose a player that you’ve only taken for four or five weeks.
“But we wish him all the best because he’s a super player.
“We knew we had a player at 15 years of age and he’s come on leaps and bounds. He had a setback, but he’s come back from it and he’s a top quality player.”
