Actually the longest you can stack shield is 14 days. (After the initial beginner shield period)

1+2+7+1+2+1 = 14 days. At the end of the 10th day, you can buy another 1 day shield. You can buy the 1 day twice. So you can spend 850 gems and get 2 weeks (14 days) of shield if you login on the 5th and 10th day.
