Married Beyonce Knowles has two engagement rings, and switches to a less expensive "fake" when she's onstage and out in public.
When the superstar's spouse Jay-Z popped the question last year (07) he presented her with a stunning $5 million (GBP3.3 million) 18-carat diamond ring, and also gave her a much cheaper $5,000 (GBP3,300) imitation for concerts and parties.
A source tells Star magazine, "Even though Beyonce's real engagement ring is insured, she doesn't always feel comfortable wearing such a valuable stone."
