Meaning of jadeitový kameň
Jadeitový kameň is a natural gemstone. It is the gemstone form of the mineral jadeit. Jadeite belongs to the pyroxene mineral group. It is known for high strength, high density, and long durability. Gemology and mineral science define jadeite based on its chemical makeup and crystal structure.
Mineral structure and classification
Jadeitový kameň has the chemical formula NaAlSi₂O₆. It forms under strong pressure deep inside the Earth. The crystal system is monoclinic. Jadeite usually appears as compact stone masses instead of clear crystals. This structure gives jadeite strong resistance to breaking. Mineral classification systems list jadeite as a clinopyroxene.

How jadeitový kameň forms
Jadeitový kameň forms only in rare geological conditions. It develops under high pressure and low temperature. These conditions exist in subduction zones. A subduction zone forms when one tectonic plate moves under another. The main source of jadeite is Mjanmarsko. Another important location is Motagua Valley. Scientists confirm this formation process through geological research.
Physical properties of jadeite
Jadeitový kameň has stable physical properties. Its hardness ranges from 6.5 to 7 on the Mohsova stupnica tvrdosti. Density ranges between 3.30 and 3.38 g/cm³. The refractive index is about 1.66. The surface shows a glassy or slightly oily shine. These values help experts identify real jadeite.
Color types of jadeitový kameň
Jadeitový kameň appears in many colors. Green jadeite contains chromium. Lavender jadeite contains manganese. White jadeite has very few trace elements. Black jadeite includes carbon particles. The most valuable color is bright emerald green, called imperial jadeite. Color purity and even color distribution increase value.
Difference between jadeite and nephrite
Jadeitový kameň is often confused with nephrite. Jadeite has a grainy structure. Nephrite has a fibrous structure. Jadeite is denser and more transparent. Nephrite is softer in appearance. Gemologists use these features to tell them apart.
Cutting and treatment of jadeite
Jadeitový kameň requires special tools for cutting. Diamond tools shape the stone. Polishing improves surface clarity. Experts classify jadeite treatments into three groups:
| Jadeite Type | Description | Industry Name |
|---|---|---|
| Natural | No treatment | Type A |
| Stabilized | Polymer filled | Type B |
| Dyed | Color enhanced | Type C |
Cultural and historical importance
Jadeitový kameň played an important role in history. In Central America, the Mayovia used jadeite for rituals and symbols of life. In China, jadeite became important during the dynastia Čching. People used it for seals, jewelry, and ceremonial objects. Archaeology supports this historical use.
Market value and demand
Jadeitový kameň value depends on color, clarity, texture, and origin. Stones from Myanmar are most valuable. Transparent green jadeite reaches the highest prices. Asian gemstone markets dominate jadeite trade. Auction records show strong and stable demand.
