Derek Jeter is engaged, and you can almost hear the women sobbing! The 41-year-old former baseball player and the 25-year-old Sports Illustrated model Hannah Davis have been linked for nearly three years, but always kept their relationship under the radar. But now that he's finally found a woman to make him put a ring on it, just how much did that ring cost him? According to Forevermark Diamond Expert Kristen Trustey , Hannah's engagement ring had quite the hefty price tag attached to it. Trustey told E! News that Hannah's engagement ring looks to be a classic round brilliant solitaire diamond ring of approximately 4-5 carats, set in platinum or white gold. And assuming that Derek sprung for a center diamond of the highest quality in terms of clarity and color, Trustey estimates the value to be between $350-$450K."
