Adular / moonstone - cut stones, cabochons, mineral jewelry


Adular/moonstone is today one of the most precious gems, thanks to a unique appearance that is best described as a luminous foggy moon. Gemologists call this phenomenon adularescence. This gentle fluorescence of the stone is caused by the small inclusions of various metals and chemical compounds with different refractive indices. Individual layers of inclusions and incident rays create the impression of colors and lights as if they were coming from within the gem.
In addition to the famous Swiss mines, lunar stones are also collected in Sri Lanka or India. Monthly stones from Sri Lanka have the most beautiful colorful luminous inclusions and are among the most precious varieties of this gem. In India, interesting rainbow lunar stones with the inclusion of a whole spectrum of colors are found.



Aquamarine is a hexagonal mineral, beryllium silicate (chemical formula Be3Al2Si6O18). The name of the mineral is derived from the Latin aa marina (sea water).

Like the sea level, aquamarine can have different shades of blue, from light tones to green tones to dark blue. The louder the blue tone, the higher the aquamarine value. Most aquamarines, however, have the characteristic light blue color, which is paradoxically the most sought after in the jewelery industry.

Ametrine - cut (jewelry), top quality, Minerals-stones


Ametrine - also known as bolivianite - is a natural gemstone made up of a combination of amethyst and citrine. The vast majority of ametrines come from Bolivia, but are also found in smaller quantities in Brazil and India. The color of the crystalline quartz depends on the crystallization temperature and is due to the different degrees of oxidation of the iron.


Amethyst is a mineral, a variety of quartz of various shades of purple color. Amethyst is counted among precious stones, is a favorite material for making various ornaments and jewelery. It is mainly found in the cavities of basic rocks (geodes). Amethyst has a color from purple to purple. Some amethysts are transparent, others are translucent, other opaque, opaque. Because of their color they are very popular.

Amethyst is one of the most precious gems of the mineralogical group of quartz, and its purple hue is due to the trace amounts of iron and aluminum. Purple color has been considered one of the symbols of the royal status since time immemorial, so amethyst has become part of a number of coronation jewels.

The jewelery has been of amethyst since ancient times. Amethyst beads are known from the ancient civilizations of Mohendzhador, Egypt, Sumer, and Baktrie in Afghanistan and Tajikistan.

As grenades (Hagones, 1250) we refer to the group of cubic minerals, non-silicates with a complicated chemical formula of the general form X3Z2 [SiO4] 3. The name comes from the Latin granatum malum - pomegranate. They generally consist of rhodododecahedric and hexaoctoedric crystals. Grained and compact aggregates are less common. There are individual grains or smoothed pebbles in the alluviums. The most famous varieties include Almandin, Grosular (light green to amber or deep brown), Hesonit (variety of grosular, honey yellow), Pyrope (blood red to black), Spessartin (dark red to brownish red), Uvarovit (emerald green). The most precious are the pyropes with the color change effect of alexandrite, in daylight and artificial lighting, very expensive are emerald green tsavorites from Tanzania, demantoids from Russia, cheaper are orange spessartins, sought after is rhodolite, rhodolith garnet, pyralmandine is a mixture of pyrope and almandine. raspberry colors.

The name consists of the Greek words χρυσός (chrysos) = golden and βήρυλλος (berylos) = beryl, which describe the color of the mineral.
Despite the similarity of names - chrysoberyl and beryl, they are two completely different gems, although both contain beryllium. Chrysoberyl is the third hardest, frequently occurring natural gem and lies at 8.5 on the Mohs mineral hardness scale, between corundum (9) and topaz (8). Ordinary chrysoberyl is yellowish green and transparent to translucent. If the mineral has a good light green to yellow color and is transparent, it is used as a gem.

Kunzite - polished jewelry stone, gemstone (top quality)


Kunzite (like hiddenite) is a variant of the mineral Spodumen.

Kunzit was discovered in 1902, and was named after Tiffany & Co's main jeweler, George Frederick Kunz.

It most often occurs in shades of light pink, but more vivid colors are possible and can reach rare shades of vivid purple to violet. It is colored in this way due to the content of small manganese particles. When exposed to intense light, the color may fade over time, so it is better to protect both jewelry and crystals from light and store it in a case or box.

The hardness of the kunzite is 6.5 - 7 on the Mohs scale.

Olivine (peridot)

Olivine (peridot) is a rhombic mineral with a variable proportion of magnesium and iron depending on the conditions of its formation. It is the iron that causes the stone to turn green. Olivine is formed by crystallization from magma with a low silicon content such as basalts or gabbro.

Ruby is a pink to red gem consisting mainly of corundum (Al2O3) mineral with chromium coloring. The degree of hardness on the Mohs scale is 9. Among the largest deposits of rubies are mainly Africa, Asia (Burma), Australia, Greenland, Madagascar. The oldest deposits of rubies are alluvial rivers of southwestern Sri Lanka (Kaliganga River) with the old center of Ratnapura. Rubies are in demand magical and jewelry minerals. Their color is orange-red, raspberry, faint red, deep red, red, like blood - also known as "pigeon blood" - so colored rubies are the most precious! Ruby is one of the most valuable gemstones whose value can sometimes even exceed the price of roughly equal diamonds.

Natural sapphire - cut stones, investment gemstone, Minerals-stones


Sapphire (Hebrew name) is a mono-crystal of alumina (Al2O3), a mineral called corundum. Whilst corundum consists of pure alumina, the sapphires always contain a mixture of other elements (iron, chromium, copper, magnesium, etc.) that supply it with blue, red, yellow, pink, purple, orange or greenish color. Among the sapphires are all gems, which are corundum varieties except red - also called ruby.

Sapphires are characterized by a variety of shapes and processing. The most precious are the oval shapes in which the star effect of the gem stones. Fancy and Emerald Shapes are also common. For less pure sapphires, the shape of the kaboson is used.

Sunstone - cut, jewerly quality


Sunstone is a kind of dull, translucent, sometimes even transparent feldspar. Due to the small platelet mineral inclusions within the stone (usually those of copper, hematite or goethite) that produce bright metallic flashes, we can see an optical phenomenon called "aventurescence." and transparent with inclusions. The world's best-known sites include the USA, Mexico, Tanzania, India, Sri Lanka, Australia, but caution is needed when shopping, sun stone ranks among rare minerals and precious stones, and is often confused with cheaper merchants synthetic avanturine.


Sinhalite is a borate mineral with the formula MgAl (BO4), hardness 6.5 - 7 Mohs scale.
This precious gem was first discovered in Sri Lanka (Ceylon) in 1952 and was named after its site - "Sinhala", which is the Sanskrit name for Sri Lanka. (Burma) The most common color of Sinhalite is white to gray, gray-blue or various shades of brown - from light to dark, and more rare are the shades of yellow.


Emerald, the chemical formula Be3 (Al, Cr) 2Si6O18 (beryllium aluminosilicate), is a hexagonal mineral. Emerald is the best known and most valuable variety of the mineral beryl. The most famous and valuable - thanks to its unmistakable deep green color - are the emeralds from Colombia. Other important sites include Brazil, Zambia, Namibia and Russia.

Tanzanite - cut gem quality


This beautiful blue-violet stone was discovered in Tanzania by a group of indigenous people - the Maasai. Some of the herders have noticed interesting stones that turn blue when exposed to high temperatures, such as fire or lightning. The Maasai believed that tanzanite was a symbol of birth, so this gemstone became a popular gift for the birth of the first child.

Tanzanite has been enthusiastically celebrated as the “jewel of the 20th century” since its discovery in 1967. The gem was made famous worldwide by Tiffany & Co., which also chose its name from its only site, East African Tanzania. are heat treated.


Spinel is a cubic mineral belonging to the spinelids group.
The name probably comes from the Latin spina - ton, according to sharp octahedral crystals.

Spinels, however, offer the same variety of colors as sapphires. The historically oldest spinel site was the giant infusions of Sri Lanka. Around 500 BC the first Badakhshan, now Tajik pink to wine spinels, may have been found, admired by the Persian kings and saves. Around 1000 AD the extraction of these spinels from the Pamira and Hindukse intersections has grown, and from there a balanced spinel is also adorned with many distinguished European jewels. Spinel is softer than corundum, but it is a beautiful stone, healers are very protective, and he enjoyed great popularity in India.

Tourmalines are complex borosilicates of aluminum and many other elements, mainly sodium, iron, magnesium or lithium. In nature, these elements in the crystal structures of tourmalines are represented in a variety of ways. Today the chemical composition distinguish 14 kinds of tourmaline (schorl, dravite, ELBAITE, welcome liddicoatit, buergerit, feruvit, chromdravit, foitit, magnesiofoitit, olenit, povondrait, rossmanit, vanadiumdravit). These are mixed with each other, so the correct assignment of a sample of turmaline to a particular species is usually possible only after a thorough chemical analysis, according to the predominant component. The chemical composition of tourmaline often changed during its growth. Tourmalines commonly have different chemical composition in the middle of the crystal and others at its edges, or differ in chemical composition at the ends of the columnar crystal and in the middle of the column. The most widespread tournaments are scorching, starving and elbait. Perfectly combines the lead with the predator (so-called skoryl-dravitová) and the skull with the elbaite (a series of skoryl-elbaitová).
Tourmaline forms acicular and columnar crystals longitudinally grooved in cross-section triangular or hexagonal, or stébelnaté forms, acicular or even felty aggregates. Tourmalines are glass-glossy to matt, on uneven to last-lasting fracture they are vitreous to greasy. They are transparent, translucent to opaque. Most common are black, brown, dark green, dark blue, or pink, red, light green, light blue, etc.

Smokyquartz (polished, gem quality)


Smokyquartz (SiO2) is a variety of quartz (silica), which is colored by an admixture of aluminum, sodium and lithium. It crystallizes in an arch system and has a hardness of 7 on the Mohs hardness scale. A typical crystal shape is a hexagonal prism with two arches, in which the prism surfaces are grooved horizontally. However, twinning or growth of polycrystals usually occurs, but we also encounter single crystals.
