If you missed the Lady Heart Diamond Collection exhibition, you're in luck, as the Los Angeles Natural History Museum has extended the temporary show until December 1, 2013. The exhibition features five red, pink, orange, yellow, and blue diamonds. The rare diamonds are all heart shapes ranging from 1.71 to 2.28 carats–set in custom-designed jewelry pieces–at the museum's "Gem Vault" in the Gem and Mineral Hall.
