A Diamond Tile (or also referred to as RC Tile and white rock) is often found deep around normal Tiles. They can be found on every map, except Freeports. Finch I, Finch II, Sparrow, Canary, and The Pits contain diamond tiles.
In the three "normal" maps(Both finches, Sparrow I), the diamonds are placed randomly and rarely among normal Tiles. They must be destroyed with, and occasionally "tunneled" into, using Ammo, although Slug Ammo will do heavy damage to them. After destroying the diamond, the tile will randomly drop one RC Turret, Auto Turret or Burst Turret. (Note: Diamond tiles in Sparrow take more hits to destroy as they are harder.)
In The Pits, large quantities of them are found at the bottom of each pit, covered over by many Boulders. They require Yank Ammo and/or Punch Ammo to move the boulders and reach the bottom.
In Canary, they are scattered around the map with yellow bots. They are very common on this map.
