I read this twice but something still doesn't make sense to me.
"He started to suspect one of his employees, Kimberly Spicer-Vanzant. She recently had the store's craftsman place a large diamond into a ring she owned, so the store owner asked her to bring in the ring to check it out.
"When she brought her ring in," EPD Detective Dan Winters said, "it had a cubic zirconium diamond, which is not a real diamond, set in there. And they knew at that point that they had a theft."
If anyone reading the story can make sense of it, please explain in the comments. Thanks!
