Nodes
Every gem except Diamond and Prismatic Shard can also show up in crates and barrels in the Mines. Gem Nodes, on any floor plus Skull Cavern, the Quarry, and the Volcano Dungeon, can drop Amethyst, Aquamarine, Diamond, Emerald, Jade, Ruby, or Topaz. The Geologist profession gives a specific gem node a 50% chance to spawn twice the gems.
Diamond and Prismatic Shard are the two that stay out of ordinary mine crates. Any monster can drop a Diamond at 0.05% after the bottom of the Mines, the same extra pool that can drop a Prismatic Shard.
