Chakvetadze broke twice in each set against Larsson, who was playing in her first final and who missed all three break-point chances in the second set.
Chakvetadze's previous title came in Paris in 2008. A top-five player in 2007, she has fallen to No. 103 in the rankings.
The 21-year-old Larsson reached her first WTA quarterfinal earlier this month in Prague.
