Diamond Dust

The Diamond Dust (ダイヤモンドダスト) is a Keychain for Sora's Keyblade that appears in Kingdom Hearts Final Mix and Kingdom Hearts: Chain of Memories.

In Kingdom Hearts Final Mix, Sora is rewarded with the Diamond Dust for clearing the Gold Match.

Design
This Keyblade appears to be made of ice, and both the teeth of the blade and the Keychain's token are snowflakes. It bears some resemblance to the Oathkeeper Keyblade. The chain part of the Keychain is attached to the Keyblade by a gold ring and is made up of gold links, except for the first link, which is shaped like the Ice Titan's head. The Keyblade's name is based on the traditional attack of the Final Fantasy summon, Shiva.

When Diamond Dust is swung, it leaves a trail of frozen mist in its wake.
