Jasper is the twelfth stone in the Breastplate of Judgement; the first Foundation
Stone of the Heavenly Jerusalem; and is assigned to the Angelic order of the Thrones.
"Jasper is the primary foundation [stone] of God's Church.
It represents those who hold always their faith of God and never depart
from it or wither away, but always they remain fresh in it...
