• Despite their naming, this card was released after "Luster Dragon #2", which was originally released as "Luster Dragon". "Luster Dragon #2" got its name change shortly after this card's release.
    • The likely reason both cards' names were initially translated to "Luster Dragon" was because both cards' Japanese names contain gemstones in their names, "Sapphire" and "Emerald" respectively.
  • This monster appears in the artwork of "Star Blast".
  • This monster has an anime-only red counterpart, "Ruby Dragon", which has 300 more ATK and DEF.
    • The fact that they look so similar may be a reference to the fact that sapphires and rubies have the exact same crystalline structure, but different chemical makeups, resulting in different colorations.
