Atlantic Jewel is ready to make her comeback in the Memsie Stakes but Mark Kavanagh says he's left a lot improvement in the glamour mare.

Atlantic Jewel makes her long-awaited return in the Group One Memsie (1400m) at Caulfield on Saturday with an unbeaten record in seven starts.

Kavanagh said he probably wouldn't have brought the mare back to the races after her injury lay-off if he thought she couldn't return and be a spring drawcard.

The trainer also left no doubt as to how special he rates the dual Group One winner.

"There's no other horses like her. Nothing," Kavanagh told reporters on Thursday.

"She is special."

Atlantic Jewel is an odds-on favourite for the Memsie but Kavanagh said protecting her unblemished record wasn't a concern for him.

"I've never lost sight of the big picture and the big picture is in October (the Cox Plate)," Kavanagh said.

He said Atlantic Jewel was "no Black Caviar" because Atlantic Jewel was being aimed at the Cox Plate.

"She's no Black Caviar sprinter horse, she's getting ready for a 2000-metre race so it would be foolish to have her totally cranked up for first-up," he said.

The Peter Moody-trained Black Caviar retired earlier this year with 25 wins from as many starts.

Atlantic Jewel hasn't raced since the All Aged Stakes in April last year with a tendon injury keeping her out of racing.

The trainer said he was mindful of leaving improvement in the mare for the spring.

"The temptation and the pressure may very well have tempted another person with a seven out of seven horse to have it at one hundred per cent (on Saturday) with no improvement, but I haven't done that," Kavanagh said.

Atlantic Jewel is $1.95 favourite with TAB fixed odds with It's A Dundeel the only other runner under double figures at $5.50.

Kavanagh said he had done everything to try to ensure Atlantic Jewel returns to her best.

"I expect that she should run a good race and I'm hoping she pulls up sound and goes forward for the spring," he said.

Australian Cup-winning stablemate Super Cool also resumes in the Memsie with Kavanagh saying the gelding would likely take a run or two before he reaches his best.
