origin of name | Like many stones, the name of this mineral comes from the merger of two Greek words. Mineralogists, examining the stone, noticed that its structure resembled scales, so they took the word “lepis” - scales - as a basis. For the second part of the name they used the word “lithos”, which translates as stone. Literally translated, it turns out that lepidolite is a scaly stone. |
Lepidolite is a mineral with a scaly structure, which is why it received such an unusual name. The term “lepidolite” is made up of two Greek words: “lepis” means “scale”, and “lithos” means “stone”.
Lepidolite deposits
Lepidolite deposits are quite widespread.
The pink-colored mineral is mined in the Czech Republic, Sweden, USA, Afghanistan, Pakistan, and Mozambique. Its large mines are also known, located in countries such as Australia, Brazil, Madagascar, Germany, and Italy. — Advertising —
As for Russia, lepidolite is mined here in the Urals, in the Krasnoyarsk Territory, in Transbaikalia, and on the Kola Peninsula.
The formation of deposits of this gem occurs under the action of lava, which breaks out at the junctions of the lithospheric layer in mountain ranges, on granite deposits.

History of lepidolite
The name of the mineral “lepidolite” indicates its characteristic scaly structure.
It is translated from Greek as “scaly stone.” The discoverer of the mineral was the German chemist Martin Heinrich Klaprotha, who initially gave the find the name “lilalite.”
A little later, the stone was renamed “landrin” because of its characteristic lilac-lilac hue. The gem received its last name, which has stuck with it to this day, only at the end of the 19th century, when scientists studied its properties and structural features and found out that the stone is a closely welded scaly mica. Its individual scales are flexible and thin; they are very easy to bend, after which they regain their original appearance. A monolithic fusion of such scales is already a fairly strong structure. In addition to plates, it can be made in the form of a rosette and cone-shaped grain.
Compatibility with other stones
Lepidolite cabochons look good framed in gold and silver. When it comes to stones, it is best to pair this natural wonder with semi-precious gems so that its beauty is enhanced rather than overshadowed.
The mystical power of the stone will be more pronounced if it is adjacent to the following minerals in the decoration:
- kunzite;
- rubellite;
- rose quartz;
- charoite;
- pink beryl.
The color scheme will be delicate, enlivening any formal clothing.
Physicochemical characteristics of lepidolite
— Advertising —
The chemical composition of lepidolite is quite variable; the stone may contain varying amounts of potassium, lithium, aluminum, silicon oxides, as well as fluorine. It is also characterized by iron, manganese, calcium, sodium, cesium, and rubidium as impurities.
Lepidolite crystals usually have a purple center and white or light pink edges, with occasional shades of gray and yellow appearing in its color. They are distinguished by a glassy or pearly luster, transparent or translucent, with a monoclinic system.
Lepidolite most often forms as layered prismatic crystals with convex pinacoidal discontinuities, pseudo-hexagonal “books,” and mica or granular masses.
The cleavage of the mineral is perfect, the fracture is uneven. The hardness of the crystals on the Mohs scale is 2.5. The density is 2.8-2.90 g/cm3.
Associated minerals are quartz, feldspars, spodumene, amblygonites, and tourmalines.
Varieties of mineral
Although one of the names of the stone mentions purple, its color is not limited to this color. There are nuggets in the following shades:
- white;
- violet;
- violet-gray;
- lilac;
- yellow;
- grey;
- pink;
- peachy red.
Sometimes the name of the mineral is used, depending on the shade. Light stones, close to the color of lavender, are popularly called lavanderin, brighter ones - lilalite. The crystal with a pronounced layered-spherical structure is officially named the Eye of Barbot (after the name of the famous geologist).
Sometimes the color of the mineral is concentrated in the center, while the edges remain light. The surface of lepidolite sparkles like pearls, but there are also duller specimens. In any case, the surface of the stone seems to be covered with gloss - albeit slightly, but shiny.
There are nuggets of various shapes: in the form of a plate, a cone or a layer resembling a rosette. The stone may look translucent, but it should not be completely visible in sunlight - this is a sign of a fake.

The magic of purple scales
Since lepidolite is one of the later discoveries, little studied and not described in sufficient detail, its magical abilities did not attract esotericists for a long time. However, the younger generation of magicians and psychics became interested in the stone, using the mineral at first for meditation, gradually studying other magical facets.
Today, esotericists focus on the following magical aspects of the use of lepidolite:
- The mineral acts as a sedative, which allows the owner to escape from the routine, concentrating on the main thing. This helps you make important life decisions without feeling discouraged or depressed.

Price
Despite the rarity of the stone and the complexity of its processing, jewelry made from pure lepidolite (that is, without combination with quartz) can still be purchased. Since costume jewelry is mainly made from this mineral, the cost of jewelry made from it is low (price/rub.):
- pendant without frame - from 2000 ;
- alloy earrings - 500–2500 (sometimes up to 9000) ;
- ring - 700–5000 (depending on the jewelry alloy);
- beads made from small beads from Brazilian mineral - from 3500 ;
- egg 60 x 40 mm - from 3500 ;
- cabochon size 42 x 19 x 1 mm - from 350 .
Applications for lepidolite
Most mined lepidolite is used industrially to produce lithium, the lightest metal needed for the production of batteries, laser machines, pharmaceuticals, and even for the disposal of nuclear waste.
Lithium is also needed in the production of opal and white glass. As for jewelry, in this case, due to the scaly structure and high cleavage of the crystals, it is difficult to process lepidolite. In addition, individual high-quality crystals suitable for cutting are rare. Specimens of unusual shape and color are valued in mineralogical collections. Therefore, the mined mineral is carefully sorted in search of jewelry and collectible samples.
Large specimens of lepidolite are cabochon cut, but they are rarely used in jewelry; they are used to make boxes, snuff boxes, flowerpots and other round and spherical interior items, which, after processing and polishing, are distinguished not only by their beauty, but also by their high strength and resistance to wear .
How to care for lepidolite
As a fragile stone, lepidolite requires careful and careful handling. Products with it are stored in separate boxes, wrapped in soft cloth. To clean, use a mild soap solution, after which the product is rinsed in cool running water and dried well with a soft cloth.
Lepidolite and zodiac sign
Lepidolite is best combined with representatives of the zodiac sign Libra. These people are known to be subject to mood swings and frequent fluctuations in decisions. Thanks to its properties, lepidolite helps them find peace and balance, inner harmony and agreement with themselves.
What astrologers say
According to astrological material, lepidolite correlates with the sign of Libra, which belongs to the air element. However, all representatives of air signs are characterized by lability of mood and some lack of understanding of their own needs. Jewelry and amulets made from this stone contribute to finding inner balance, and as a result, stabilizing relationships with loved ones, colleagues, and just acquaintances.
In principle, to one degree or another, lepidolite is suitable for all signs of the Zodiac. However, there are cases of individual intolerance. This becomes noticeable in the first few minutes of interaction with the stone. If a person does not immediately feel ill, then there is no “allergy”.
Interesting facts about lepidolite
In jewelry, when polishing and cutting lepidolite samples, two main problems arise: perfect cleavage and low hardness of the stone. During grinding, the mineral easily crumbles, especially when structured from finely scaly aggregates. For this reason, jewelers often do not use independent lepidolite intergrowths, but process quartz with its inclusions. Such specimens of quartz can be easily given a rectangular, spherical or other shape, and the lepidolite is not damaged and can be admired.
Quotes
Collectors are chasing well-cut specimens of non-standard colors, especially when intergrown with other minerals. For each such sample, unimaginable sums of money are paid.
