Chrissy Teigan, $200,000
Almost losing her ring due to airport security, John Legend was able to keep his planned proposal a secret until the couple landed in the Maldives where he offered Teigan a 5 – 6-carat diamond in a cushion-cut delicately placed in a pave-diamond white-gold setting. The ring is estimated to be worth between $150,000 and $200,000. Brilliant Earth features similar rings priced from $1,000 – $1,600.
