KAlSi3O8
Moon-silver light and the quiet inner knowing
Adularia was named in 1780 by Ermenegildo Pini after its type locality, the Adula massif of the Alps near the St Gotthard region on the Swiss–Italian border. The optical term adularescence — the floating blue glow of moonstone — takes its name directly from this mineral.
Adularia is a low-temperature variety of potassium feldspar, KAlSi3O8 — the same composition as orthoclase, but grown slowly and cool in Alpine fissures and hydrothermal veins. It forms glassy, often twinned prismatic crystals, colourless to white, with a hardness of about 6 to 6.5.
It is the moonstone feldspar: translucent specimens show adularescence, a soft blue-white shimmer that seems to float just beneath the surface, caused by light scattering off fine internal layering. It is also a recognised indicator of low-temperature, epithermal gold-bearing systems.
Named in 1780 from the Adula Alps of Switzerland, adularia is the classic mineral of Alpine clefts — the glassy feldspar that lines fissures and schist cavities in the high mountains, grown by cool circulating waters.
It also forms in low-temperature epithermal veins, where its presence helps geologists recognise the kind of system that can carry gold.
Translucent adularia shows adularescence — a soft blue glow that floats beneath the surface like moonlight on still water.
A low-temperature feldspar grown slowly in the fissures of high mountains by cool circulating waters — the gem of the Alps.
Its growth in cool epithermal veins makes adularia a signpost for the low-temperature systems that can carry gold.
"The mind is the cause of both bondage and liberation. To control it is the greatest victory."— Trailanga Swami
Adularia works at the heart — the centre of the chakra system, the body's main place for the healing of emotion, where a person connects to others and to life in a direct, unfiltered way. Its frequency sits in the middle range and works the nearer layers; its transmission is gentle and it stays a fair while. This is the seat of its old reputation as a stone of the feminine “Goddess” energy, of intuition, and of hormonal balance and the body's natural cycles — fitting for the moonstone feldspar, whose shimmer rises and fades like the moon itself.
As a Healing stone its energy settles on the heart and dissolves what is held there rather than moving it about; at this gentle frequency it works on the body and the emotions, softening the swings and disturbances that throw the inner cycles out of true. Because it carries Love, the frequency centres fully into the heart and radiates from there, filling the work with kindness and gratitude; and as a stone of Life it feeds that centre with quiet vitality.
"Happiness is your nature. It is not wrong to desire it. What is wrong is seeking it outside when it is inside."— Ramana Maharshi
Intuition, in this stone, is simply that inward turn made easy: when the heart is calm and balanced, the quiet inner knowing that was always there can be heard. And beneath it waits Joy — the thoughtless, unfiltered gladness that surfaces of itself once the emotions settle and the moonlit stillness returns to the heart.
