Stronger than radiant gems but excessively difficult to produce. Radiant gems require ample amounts of gold, arcellium, and jade as the base, and then you take a bunch of magicite and mana to transfer the magic enhancing property of the arcellium, as well as the radiance of the gold, into the jade. With this, you produce an abundantly expensive enchantment gem that uses a full bar of mana to embue something, and the effects are based on various factors like the user's magic manipulation instead of just whether or not the enchanted item is made of arcellium or manaweave, but that does help improve the end product further.
If the user's magic manipulation is less than ideal, the end product of this enchantment will be worse than an ordenary enchanting gem, but if they have an abundance of intelligence and stuff, then their enchantments with a radiant gem will be spectacular. Beware though.

With the addition of radiant enchantment gems, comes the "gem of arcane explosion" which causes every enchanted piece of gear attached to the wearer to destabilize and explode upon death. The explosion damage depends on the total % bonus of all enchantments equipped, and the explosion radius depends on the number of equipped pieces of enchanted gear. The purpose of this is to prevent the looting of enemy radiant gear. Luckily, like the exploding turrets, there is a visual effect and sound for the arcane explosion. The subject will glow white hot for a few seconds while a ring of radiance slowly expands toward their explosion radius. During this there is the sound of destabilizing magic. After the ring reaches the marker, the sound will intensify as the body begins to blink with increasing rapidity until it explodes.
