The spring campaign of boom mare Amelia’s Jewel remains unclear, despite been given a clean bill of health after blood tests were taken on Monday.

Veterinary tests have cleared the four-year-old of injury following her shock performance in the G1 Toorak at Caulfield on Saturday when unplaced.

Amelia's Jewel, unbeaten in Melbourne after the Let's Elope Stakes and Stocks Stakes, ran 9th in the Toorak, the worst performance of her outstanding career.

Trainer Simon Miller hopes Amelia's Jewel can show the same resilience that saw her bounce back from a virus to win the Group 1 Northerly Stakes last year.

Ruling out the Cox Plate at Moonee Valley in a fortnight, Miller said Amelia's Jewel will either run in the Golden Eagle in Sydney or return home to Perth.

Although her blood tests came back clear, Miller said Amelia's Jewel was not at her best after the Toorak run at Caulfield.

"She's still not eating right which is not great," Miller said to The Races WA.

"She's still not breathing fire, so she'll have a light week in Melbourne.

"I'm hoping she can bounce out of it and I can increase her work next week.

"It's frustrating, but good that the tests found nothing major."

Amelia's Jewel was a surprise nomination for Perth's rich Ascot Pinnacles carnival yesterday.

She was among strong nominations for $1.5 million Winterbottom Stakes and $1.5 million The Gold Rush.

"It's a back up if she comes back home," Miller said.

"If she can't get to the Eagle it gives her bit of time before the Perth races."
