that needs to be changed, the "presumably Pink Diamond" being confirmed.

It is revealed in "Monster Reunion" that the Diamonds were the ones responsible for the Corruption of almost all remaining Gems on Earth.
 * Centipeetle only drew three diamond symbols when she was asked who or what caused the damage to her and the other Corrupted Gems, so one of the Diamonds was not involved with this weapon, presumably Pink Diamond, who had faked her death and become Rose Quartz, while the damage was caused at the end of it. Centipeetle's drawing depicted the original symbol of adjacent diamonds (with Pink Diamond's removed) rather than the modern symbol of overlapping triangles.
