Centuries ago, Gunmar undertook his first kill by shattering the Quagawumps' beloved king, who was then known as the Shattered King.
In "The Shattered King", Team Trollhunters visit the Quagawump Marshlands to find the Killstone, but thanks to Toby's overconfidence and Blungo's interference, Angor Rot crashes their party and steals the Killstone (but loses his Shadow Staff, which is taken by Claire).
Later in "It's About Time", Jim uses the Kairosect to retrieve the Killstone from Angor and later cleaves it in "Wingmen" and places it into his amulet. The Killstone unlocks the Trollhunter's ability to summon a warrior's shield.
In its natural form, the Killstone is a green diamond-shaped emerald.
In its cleaved form, it's pretty much the same shape, only much smaller.
