- The effect of this card references light passing through a gemstone and giving it a different color.
- Since "Gem-Knight Crystal" is somewhat similar to "Elemental HERO Neos", this card may be the "Gem-Knight" counterpart of "Elemental HERO Neos Alius".
- They are both Level 4 Effect Monsters.
- This card has 100 ATK and DEF less than "Neos Alius".
- Also they both can support their older forms ("Neos Alius" gains the name of "Neos" while "Alexandrite" Summons "Crystal").
