Kim Kardashian's Engagement Ring from brand-new fianc Kris Humphries is a serious piece of jewelry. The 20.5-carat Lorraine Schwartz-designed sparkler features a 16.5-carat emerald cut center stone flanked by two 2-carat trapezoids... and cost a whopping $2 million. Even for an NBA player like Humphries, that's one expensive rock.
