Heidi Klum's Engagement Ring

Supermodel Heidi Klum proudly showed off her engagement ring at the launch of her television show Project Runway in New York. The ring is set with a 10-carat oval yellow diamond (some sources list it as 8 carats) and was presented to her by her fiancÚ Seal, for whom it is going to be the first marriage. The singer and the supermodel became engaged at a Canadian ski resort during the winter of 2004, and Seal tried to make his proposal as romantic as possible. He built an igloo high in the mountains for the special moment and hired a helicopter to take Heidi there.

Heidi Klum is no stranger to exotic diamonds and jewelry. She has modeled several Mouawad 'gem bras', among them the 'Star of Victoria Fantasy Bra' containing the 60.19-carat pear-shaped Mouawad Mondera Diamond.
