Diamond Weapon is a boss in Final Fantasy VII. It is one of the Planet's many Weapons, released in response to Sephiroth summoning Meteor. The party fights it as it approaches Midgar towards the end of the game. Its attacks include a foot stomp, a blast of magical energy, and its Diamond Flash, a Gravity-based attack with a three-turn countdown that also inflicts Silence.
Once the party reduces Diamond Weapon's HP to zero, it is still approaching Midgar. Once within range, it opens fire on the Shinra Headquarters. At that same time Shinra fires the Sister Ray, which successfully pierces Diamond Weapon and destroys the barrier Sephiroth erected over the North Crater.
Defeating Diamond Weapon in the PC version re-release of Final Fantasy VII unlocks the Diamond Weapon achievement.
There is a glitch in the game that lets the player avoid fighting Diamond Weapon, but it will ruin the player's save file. If the player enters the menu and saves their game exactly when the battle against Diamond Weapon is going to start, and then loads their game normally, the Diamond Weapon has vanished. This leads the player unable to finish the game as the barrier over the crater is still intact, and the scene where the party is prompted to parachute to Midgar never triggers.
Diamond Weapon's laser ray deals 700+ damage to one target and foot stomp deals 1000+ damage. When the Weapon's HP is low it will use the Countdown. Unless killed in three rounds, it will use the Diamond Flash attack to hit all party members for 7/8 of their current HP, and inflict the Silence status. Diamond Weapon is immune to physical attacks until it is hit by two Limit Breaks, the Weapon may open up its armor allowing the party to use physical attacks. It then starts a countdown from 3, during which it is immune to magical attacks and only uses its laser ray. Once this is over, the immunity is reverted to physical, and Diamond Weapon casts Diamond Flash, dealing massive Gravity damage to the party, and inflicting Silence. The party will also need to use three Limit Breaks, not two, to trigger the countdown.
When Diamond Weapon is defeated, it does not turn red and phase out like most enemies; the camera simply zooms in on its head and cuts to the Battle Results screen. This is because the party doesn't actually slay the Weapon; they only hold it off until the Sister Ray destroys it.
Good spells to use outside of the countdown phase are Bolt3, Trine, and Ultima. After being hit by two or three Limit Breaks, the Weapon may open up its armor allowing the party to use physical attacks. It then starts a countdown from 3, during which it is immune to magical attacks.
Diamond Flash can be annoying, as the player needs magic to continue attacking. Thus, it is advised to not use Limit Breaks; or, alternatively, bring immunity to Silence. Of course, since Diamond Flash charges Limit Breaks, the party can simply use three Limit Breaks in quick succession to restart the countdown; if they have Fire-elemental armor or the Elemental-Fire materia combo in their armor, this essentially makes it impossible to get a Game Over.
Diamond Weapon appears in Final Fantasy Airborne Brigade as an enemy during an event called "Shattered World". Its attack is Midgarbreak in a reference to its attack on Midgar.

Diamond Weapon appears as figurines in the Final Fantasy Creatures Vol 3 series that came out in 2003. The Final Fantasy Creatures collection figurines require minimal assembly and there are three types of every character: full-color, crystal, and chrome. In North America the Final Fantasy Creatures figurines did not require assembly and had a completely different package with multiple creatures per pack.
Diamond Weapon was not a battle in the game's original Japanese version and only appeared in the FMVs. Yuffie's weapon Rising Sun existed in the game data, but there was no way to obtain it.
Upon closer inspection of the FMV where Diamond Weapon is blasted, it appears to be heading away from Midgar before launching an attack on it.
In the scenes where Diamond Weapon attacks Midgar it is shown to be dusk, but when the energy blasts destroy Shinra Headquarters, it is shown to be night-time.
