Platinum king jewels are silver-coloured slimes in the shape of a brilliant diamond. On their heads, they have red-jeweled golden tiaras that extend to to their culet (the bottom of a gemstone). Like other metal monsters, their metallic bodies make them practically impervious to all harm, usually completely resisting all attack magic and most negative status ailments, and they often flee from battle before they can be defeated. If one can be defeated, it awards an exorbitant amount of experience points, typically the highest in each game and even more than a Metal king slime.
Amongst their fellow metal slimes, they typically have the highest HP, often requiring the player to land a critical hit to defeat one short of an obscene amount of good luck. Making matters worse is their ability to cast Dazzle to ensure that melee attackers never even get a chance to hit them, let alone defeat them.
Absent from the original release, platinum king jewels can be encountered in the remake's Fungeon alongside several other monsters from Dragon Quest VII, a game that preceded the enhanced remakes.

Platinum king jewel can only be encountered as a special enemy in the Monster Arena or as a Trial Gate boss. In the Trial Gate, it is faced alongside a Gem slime, Emperor slime, and a Darkonium slime. All four can transform themselves into looking like a Platinum king jewel to try deceiving the player. It has 3,000 HP, can trample the party and cast Dazzle, and naturally has its metal body that makes it highly impervious to taking damage. It drops 60,300 experience and 2,000 gold when defeated.
The Platinum King Jewel appears as a Rank X/SS metal-bodied two-slot monster. It can be created with a two-generation synthesis of two Emperor slimes and two Gem slimes.
