Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30+5 = <<30+5=35>>35 precious stones.
The total number of stones Olivine and Agate has is 35+30 = <<35+30=65>>65
Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35+11= <<11+35=46>>46 precious stones
In total, they all have 65+46 = <<65+46=111>>111 precious stones.
