Emerald Magic

Emerald Magic (翡翠の魔法, Hisui no Mahō), is one of the few gem-based magics known to Earthland. It's considered to be a form of Subspecies Magic, as it's derived from the principles of Earth Magic — using the mineral veins of the earth in order to induce such rare creations; this also makes it a form of Caster Magic as a result.

Though rarely seen, there are various practitioners of this magical form. Interestingly enough, this magic is considered to be highly valuable and popular to many jewelers, gem enthusiasts, and high-class women due to the rarity of emeralds in modern society.
