An element of timeliness and an air of superiority accompanied the first public appearance on Tuesday of a filly with a lot more going for her than most horses.

On the day that a cloud descended over the racing future of champion mare Black Caviar, the unraced filly Commanding Jewel made her public debut in a barrier trial at Wangaratta.

And the performance of the three-quarter sister to multiple Group One winner Atlantic Jewel suggested she will be a worthy member of the family.

Commanding Jewel, a daughter of Commands, won the 900m trial by 12 lengths on track rated a heavy eight.

"The heavy going was my only concern," said trainer Leon Corstens.

"But I'm very, very pleased with her."

Corstens said Commanding Jewel wasn't far from making her racing debut, but he will wait for a dry track.

"I want to make sure she gets a decent track for her first start," he said.

"I think she deserves it.

"But I haven't decided exactly where she'll have her first run."

For Corstens, the presence in his stable of a high-class filly is nothing new.

He was the original trainer of multiple Group One winner Mosheen who also had her first public trial ahead of the spring carnival this week.

Corstens' other top-class performer of recent times was Starspangledbanner who was sold to the Irish-based Coolmore organisation and became a dual Group One winner in England.
