Index | Tourmaline

Tourmaline. A mineral occurring in three-sided prisms. Black tourmaline is the most common variety, but there are also other varieties, as the blue (indicolite) red (rubellite); also green, brown and white. The red and green varieties, when transparent, are valued as jewels. The finest ones come from Maine, and are worth four or five times as much as garnets.


“If we would hold the true course in love, our first step must be to turn our eyes not to man, the sight of whom might oftener produce hatred than love, but to God, who requires that the love which we bear to him be diffused among all mankind, so that our fundamental principle must ever be, Let a man be what he may, he is still to be loved because God is loved.”
–Calvin, Institutes
