Mystery shoppers in Texas discovered a $20 million diamond ring they were not expecting when they went to buy it on Amazon.

The ring, made by American diamond giant Morgan Stanley, was discovered in the “Diamonds and Jewels” section of the website on Sunday.

The item is listed as a $5,000 ring and was originally listed for $8,000, according to Amazon.com.

A woman in her 30s picked it up and gave it to her mother-in-law who gave it back to her.

She said she was not expecting the price and she would have paid much more if she had known.

“I think that it is just a cool ring, I would be happy to buy that ring,” said Jessica Harkins.

She said she is looking forward to the day when she can wear it.
