Katie Sattler admits when she first noticed the diamond from her engagement ring was missing, she panicked.

The diamond is three carats with an estimated value of about $30,000. She said the sentimental value is priceless.

Her husband called it a rainbow-happy ending and praised the store manager, Jeff, for his honor, integrity and sincerity.
