For upgrading from bronze to silver it appears to be only half of the difference in 50. For my metal shrine I have 19 level 10 dragons and the upgrade is 16 gems. For my lightning bronze shrine I have 41 dragons at level 10 and the upgrade is 5 gems. For the air, I have 43 dragons and the upgrade is 4 gems.

So it should be... Shrines can be upgraded to Silver for 25gems or the half of the difference between 50 and the number of dragons already at level 10.
