When granite is mined, the player randomly receives one of the three sizes of granite blocks. When wearing Varrock armour and the armour effect activates, the size of the second block of granite will be the same as the first block.

There is no way that the player can influence which block size is mined. However, by using a chisel, the player can carve the larger blocks into 500g ones: four 500g blocks from 2 kg, and ten from 5 kg (first by cutting the 5 kg block into two 2 kg and two 500g blocks, and then cutting the 2 kg blocks).
