What is the name of the stone with crystals?

Man has always appreciated the beauty of gems; they attracted people with their mystery and charm. Some gems are so beautiful that you can’t take your eyes off them. Nature knows how to create amazing, enchanting things. In this product category of our store you can find a variety of crystals, druses and a large number of semi-precious stones processed by master stone cutters in the Altai Mountains. After processing, stones and crystals are transformed from simple pieces of minerals into true works of art. The stones exhibit a structure that is often very interesting and complex; the crystals begin to play with all the colors of the rainbow, captivating the eye. Buy crystals, druses of amethyst, rock crystal and others semi-precious processed stones you can on the pages of our store at affordable prices.

named after A.E. Fersman.

Height 93 cm, weight 164 kg. Found in Brazil.

Rocks of the upper part of the earth’s crust (potash and table salt, gypsum, limestone, etc.) are selectively displaced by groundwater, forming round voids of various sizes. Mineral substances enter the resulting cavity, filling the inner walls with zonal layers. These can be crystalline druses, stalactite deposits, etc. Outwardly, such an aggregate may look like an ordinary stone, but only a cross-section under a geologist’s hammer reveals a cosmic picture. A cavity with a colloidal or crystalline formation is called a geode. A geode (translated from Greek as “earthy”, “earth-like”) can be filled with crystallized minerals, druses of semi-precious stone. A geode can be of any shape, but most often it is spherical or subspherical. There are also more curious specimens: elongated, tubular, branched and even multifaceted. The bark of such a formation has the necessary hardness, keeping the crystals safe. A “GEODE” is a geological formation, a closed cavity in sedimentary (mainly calcareous) or some volcanic rocks. In nature, geodes are found in completely different sizes – from miniature “tonsils” to huge, human-sized mineral bodies. Large geodes, more than 1 meter high, are usually called caves. The most famous and largest geode in the world, the “Empress of Uruguay”, was found in Uruguay – it weighs 2,5 tons and is more than 3,2 meters long. The tens of thousands of perfect, dark purple Amethyst crystals that formed it amaze all who see it. At the moment, you can look at the geode in the Atherton Crystal Caves Complex Museum, opened by great admirers of minerals Rene and Nelleke Boissevain, and located an hour’s drive from Cairns Airport (Australia).

Shape and color.

Due to the alternation of layers and their chaotic growth, the appearance of the geode also changes. The contrast of shades of the internal content depends on the impurities present in the layers. You can often see red and brown stripes alternating with white and gray. Some geodes contain pastel shades, primarily blue and pink tones. Small and transparent mineral bodies are valued in jewelry, and the hardest stones are used in interior decoration. The largest geodes decorate mineralogical museums and private collections. Rarely found in nature are geodes with a geometrically regular shape, which arise accidentally during the destruction of a crystal on basalt. What remains interesting is not so much the fact of the proportionality of the appearance, but rather its content. Geodes in which the colored layers and central hole follow the geometry of the front side, creating a stunning interweaving of color and shape, will be valuable specimens for any mineralogist. A common type of geode is a concretion – this is the name given to minerals that are shaped like a ball. Concretions are formed, as a rule, in porous sedimentary rocks (sand, clay). The most common geodes include nodules of pyrite, marcasite, celestine, gypsum and calcite. Crystals are valued for their unique radial-radiant structure. Also of particular interest today are ferromanganese nodules that are actively forming on the ocean floor. It is precisely such units that can become one of the sought-after raw material resources in the future.

Magical properties.

Geodes filled with crystalline gem druses are the most valuable to collectors. Such minerals are no longer used as decoration, but as museum exhibits. Geodes with amethysts are especially popular. They are like caves from fairy tales, filled with transparent crystals. The largest of their representatives are preserved at the site of discovery in the form of natural attractions. By the way, the name “amethyst” comes from the ancient Greek language and means “non-intoxicating,” that is, according to ancient belief, the stone can protect its owner from drunkenness. The ancient Sumerian tables indicate that this stone can arouse love for the giver, even if the recipient has not previously experienced any feelings for it. Therefore, married and engaged people should not accept jewelry with amethyst as a gift from strangers. Some of the most commonly found gemstone geodes are chartreuse citrines, purple amethysts and rauchtopazes (smoky quartz). Interestingly, it was translucent quartz that in ancient times was considered one of the most powerful dark stones. Sorcerers used it to perform rituals related to black magic, and oracles used it to guess the future. According to legend, smoky quartz can bring insight into our thoughts. It’s not for nothing that Buddhists call this mineral “Buddha’s stone.” Rose quartz geodes can be considered one of the wonders of the world. Calm beauty and a bizarre shape reminiscent of an egg, a fantastic mixture of color and light – these are not all the features of the mineral. Rose quartz must be stored in a dark place, otherwise it will lose its color and turn gray. The main mining of geodes is carried out in Madagascar, Brazil, Russia (Altai), and the USA.
