Emerald Shard (Sonic X)

Emerald Shards are gems that appear in the Sonic X anime and it's comic book spin-offs.

Description
Emerald Shards are pieces of the Master Emerald  in it's shattered state. As such, they still posses powers, albeit on a weaker scale, such as empowering characters and showing characters visions.

Upon scattering, Emerald shards appear to land in random destinations with great impat, enough to cause dents in their enviorment, lodging them to the ground, as shown with one of the early pieces Knuckles finds during the Chaos Saga.

Emerald Shards can come in varying sizes, ranging from pieces as big as Knuckles himself to pieces that can easily fit in the palm of the aforementioned echidna's hand.

Trvia

 * Unlike in the games, where both the Master and Chaos emeralds are capable of being broken into shards, in Sonic X, it appears that only the Master Emerald can break apart, as any attempts at destrpying the Chaos Emeralds by charcaters only causes the Chaos Emeralds to repel them
 * The Emerald Shards are capable of losing their power/energy, whereas in the video games, they never show this weakness, and it is in fact only Chaos Emeralds that can suffer this fate.
