- This is the first "Gem-Knight" Fusion Monster to have originated from the anime.
- This card is named after lapis lazuli, a semi-precious stone known for its intense blue color (likely shown in the monster's eyes and armor).
- This stone and name is shared with "Gem-Knight Lazuli" and "Gem-Knight Lapis".
- This card's artwork is highly similar to "El Shaddoll Construct".
- Both monsters also possess similar effects; namely, "Construct" sends a "Shaddoll" card to the Graveyard while "Lapis Lazuli" sends a monster from the Main Deck or Extra Deck to the Graveyard.
- There is also a connection between "Construct" and "Gem-Knight Lazuli" (one of the Fusion Materials) in terms of monster effects. Each monster can recycle a "Shaddoll" Spell/Trap or "Gem-Knight" Normal Monster, respectively, when sent to the Graveyard.
- This card is the only "Gem-Knight" Fusion Monster with named Fusion Materials that is not Level 6.
- This monster is the original form of both "Lapis" and "Lazuli" that was split apart, which in turn gave "Lapis" their pyroxene while "Lazuli" continued to live without one.
