PHOENIX — A Phoenix woman must pay for backing out of an agreement to sell her diamond ring through eBay, the Arizona Court of Appeals says.

Julie Rohr put her 10-carat diamond ring for sale on eBay for $100,000 in 2014 and Evangelos Armiros chose the "buy it now" option, court documents say .

Rohr later canceled the agreement when she was offered a higher bid, the records say. Armiros sued for breach of contract.

The court in an opinion filed Thursday said Rohr breached a valid contract when she changed her mind on the deal.

The three-judge panel upheld a lower court ruling by deciding that the "buy it now" option amounted to a contract between seller and buyer.

The high court also validated an award of $135,250 to Armiros. He did not get the ring.
