Many centuries passed before inquisitive researchers asked
themselves a question: does an adular mirror lose the properties of iridescence
of light over the years? What determines the intensity of the decorative
effects of the gem? How did the mineral deposits form?

Mount Adoul and the Mons-Adularis mountain range that
“sheltered” it has not long been considered the only location of Adulares.
Stones of similar chemical composition, similar (in this case it is difficult
to talk about complete identity) of a physical structure and equivalent in
aesthetic expressiveness are found on all continents of the Earth.

Mineralogists carry adular to feldspar. The Ceylon spar
deposits of gem quality were once considered abundant. Good gems brought from
India. True, the colors of Indian stones are not always convincing. Mountain
formations of all continents are to some extent rich in feldspar.

However, in many cases, alien minerals appear under the guise
of an adula. The similarity between samples is limited by minimal external
similarity. In the amateur gemology environment, products from dissimilar
formations are often referred to in the same way – “moonstone” – although by
right the name “moonstone” belongs only to adular.


Adular refers to aluminosilicates of the potassium spar
group. The accustomed names are orthoclase, moonstone. The chemical formula of
the compound is K (AlSi3O8).


  • hardness up to 6.5 units on the Mohs scale;
  • density about 2.57 g / cm3;
  • colorless, yellowish, greyish, with a clear blue glow;
  • crushed white;
  • glass shine with pearl tints;
  • opaque, but translucent;
  • on a break is uneven;
  • fragile;
  • the refractive index of 1.525;

The effect
of pleochroism is absent.

The ability of a translucent stone to iridescence (see
numerous photos of the adular) is determined by the density of microscopic
ingrowth of albite into the crystalline feldspar massif. Particularly thin
plates of an adulare exhibit the ability to asterism (often one-ray).

Formed adular from silicate melts characteristic of areas of
active volcanic activity. The mineral crystallizes when the magma cools to
650-700 ° C. numerous cases of growth of adula crystals in the medium of
superheated aqueous solutions of oxygen-containing silicon and potassium
compounds are noted.

and varieties of adula

The most interesting specimens of adula were found on the
territory of gold ore mines in Russia. Gold nanoparticles are a natural
admixture in the composition of feldspar crystals mined in the Urals and

Chukchi deposits of gold give intergrowths of the crystals of
the adular with native splashes of noble metal. Often feldspar contains silver.

Baikal Adulyars amaze with the beauty of pearl reflux. In the
Irkutsk region there are moonstone crystals up to 20 centimeters in size!
However, the giants’ gem quality is small: the Irkutsk adulars are fractured,
often contaminated with brown iron oxides, and show little iridescence.

issued for adular

Due to the common optical properties, some minerals are
visually similar to adular. Belomorite is a close relative of adular, also
feldspar, but not orthoclase, but plagioclase – has the same pearlescent shine.
However, the color of white ceramics is more intense, it shows blue and green
tones, the color of sea wave.

Rainbow Labradorite is also plagioclase, and is also often
similar to adularia. The presence of a large amount of impurities colors
labradorite. Adular is more reserved, stricter, nobler than his colored

Other types of feldspar (albite, microcline) also have
similarities with adulars, but in terms of gem-quality the    y are not compared with the famous gem. The
individual varieties of chalcedony are similar to the adular color and the
degree of transparency, but this type of quartz does not show irization.

The similarity of unsuccessful batches of synthetic spinel to
adular looks like a curious thing. The features of artificial growth of spinel
crystals led to the appearance of microbubble inclusions in it. Craftsmen from
the jewelry industry immediately dubbed the laboratory marriage a special kind
of moonstone – and not unsuccessfully sold off a large part of the stock…

This adular is rare and therefore already valuable.
Impeccable gem quality gemstone is found only in isolated cases. That is why
you should not be surprised to see an adular price of ten, one hundred or even
five hundred dollars.

properties of adulara

For the healing properties of the adular to be fully
manifested, direct contact between the stone and the person is necessary. It
doesn’t matter how you wear a jewel with an adule – like a worn charm, ring or
earrings – the main thing is to ensure, if not a constant interaction of skin
and gem, then frequent touches.

The principle of action of adular on a person can be called
destructive, however, it is a question of the destruction of painful
manifestations. Over-stimulation of the nervous system, both psychogenic and
organic, is the scourge of modern times. Wearing an adular soothes a person,
relieves irritation, relaxes, helps to “disconnect” from worries.

The antistress factor of the moonstone is so powerful that
lithotherapists recommend wearing an adular even for epileptics. Good gem and
in the prevention of sleep disorders. By promoting rapid sleep, he deepens the
dream, prevents too early awakening. Dreadful dreams recede if visual and
tactile contact with the adulator has become a habit with the person.

Esotericists carry the precious moonstone to the element of
water, and healers note: adulyar is the first assistant in urolithiasis. It
helps to get rid of salt deposits in the joints and in the bile ducts. Adular
removes stagnation, activates the lymph and blood flow – especially venous.

Recommended moonstone and for those suffering from hormonal
disorders. Optimizing the drainage of tissues, normalizing the electrolyte
composition of the blood plasma, adularis most positively affect the processes
of humoral regulation of the body. Of course, the stone is not able to return
to a person the inherent reactions to a young age – the accumulation of cellular
replication errors has an effect. However, the moonstone helps to normalize the
life cycle.

The magical
properties of adulara

Use adular in magic rituals should not be. First, the
spiritual power of the stone is manifested not in creation and stimulation, but
in dissolution and relaxation. Adulyar – not an assistant in achieving goals;
Adular helps to avoid, leave, smooth, level. New age metaphysical products are the
best option for you.

Secondly, the moonstone is entirely subordinated to the
rhythm of movement of the natural satellite of the Earth. In the period of the
full moon, the lunik (the common nickname of the stone) is most effective. Old
or emerging month dramatically reduces the effectiveness of the gem. Dependence
on the night luminary is not a fully explored and not fully understood magical
property of an adulera…

Zodiac Cancers and Pisces can count on help from an adule on any day of the year. It helps the stone and Taurus. However, the rest of the signs should be careful in dealing with the shimmering gem, and Lev and Sagittarius (to a lesser extent, Aries with Capricorn) should be dispensed with adular jewelry.
