Their team symbol is a jewel droplet adorned with gold trim and two small, arced points. Its color varies according to the monster or object to which it is attached. All "Gem-Knights" are EARTH, whereas their Type varies between Pyro, Thunder, Aqua, or Rock (with one Fairy as an exception), in keeping with the cardinal elements: fire, wind, water and earth, respectively. "Gem-Knights" are further subdivided into trios: each Type includes a Normal member, a Gemini member, and a Fusion member.
While the four "Gem-Knight" Normal Monsters are shown to be unarmed, the ten Fusion Monsters wield weapons befitting their stats and effects (or lack thereof): "Gem-Knight Aquamarine" uses a bladed shield; "Gem-Knight Ruby" uses a polearm; "Gem-Knight Topaz" uses twin-bladed tonfa; "Gem-Knight Amethyst" carries a shield and what is either a wand or a slim blade; "Gem-Knight Citrine" uses a fire sword, and "Gem-Knight Prismaura" wields a lance and shield. "Gem-Knight Zirconia," on the other hand, is equipped with gigantic fists seemingly to compensate for its lack of effect, "Gem-Knight Seraphinite" uses a saber, and "Gem-Knight Master Diamond" uses a broadsword embedded with gems. "Gem-Knight Lady Lapis Lazuli", which deals effect damage, is depicted without any weapon."Gem-Knight Lady Brilliant Diamond" uses a simple sword.
"Gem-Knight" is the first and, so far, only archetype to boast six "Polymerization"-styled cards: "Gem-Knight Fusion", "Particle Fusion", "Pyroxene Fusion", "Fragment Fusion", "Absorb Fusion", and "Brilliant Fusion". Regardless, "Gem Knights" are capable of rapidly Summoning Fusion Monsters with a mere "Gem-Knight Fusion" as its ability grants the user to repeatedly return itself to the owner's hand at the cost of banishing 1 "Gem-Knight" Monster, and with the assistance of "Gem-Knight Obsidian" and "Gem-Knight Lazuli" the user is allowed to recycle "Gem-Knight" Normal Monsters. As a result, the player can Fusion Summon several times from their Extra Deck during the same turn.
