Jasper,
the first of the twelve gemstones, consists mainly of silicic acid. In
fact, the whole circle of apocalyptic gemstones is, chemically, composed
either of silicic acid or silicates, i.e. combinations of silicic acid.
What is the character of silicic acid? It is the main component (60%)
of the earth’s rocks, especially of the continents. That means that it
provides, unselfishly, the foundation on which we stand, walk and live.
On the other hand the purest form of silicic acid, rock-crystal, is of
such a high transparency that even ultraviolet rays pass through. In the
technical sense, mankind has learnt to use this unselfish transparency
of silicic acid to produce glass from quartz sands.
It is significant
that unselfishness is the basic feature of the twelve gemstones. In
jasper the pure silicic acid is colored by extremely fine grained
particles of iron oxide. Iron is the bearer of the ego force in human
blood, oxygen is the life substance. It might be concluded that in
jasper we have that kind of unselfishness which is permeated with and
borne by ego-force, the kind of unselfishness which is found in the life
and work of the greatest artists. It is the unwavering condition of
creative work. Strikingly, jasper is one of the two gemstones which
characterize the highest divine being in chapter four of the apocalypse:
“A throne stood there in heaven and one who sat on the throne. His
appearance blazed like jasper and carnelian. And a rainbow shining like
emerald encircled the throne.”

Jasper
is totally opaque. In the circle of the twelve gemstones there are six
opaque, or nearly untransparent, and six totally translucent rocks, the
opaque always facing a translucent one. The translucent gemstones are,
in a sense are more connected with thinking, the opaque with the forces
of the will. Each two opposite gemstones are, in a sense, complementary
in their qualities. Between the two may arise for our inner eye a
congenial quality which is connected with realm of feeling.
