This impressive rock crystal is a natural wonder!
With its top-quality grade and beautiful formation, it is a sought-after gemstone. Its clarity and purity make it an exceptional crystal. Three large, well-formed clear points. Such transparency is very rare, making the crystal even more valuable and desirable. The large point is slightly (about 1-2mm) chipped, which can unfortunately happen during extraction. However, this is barely noticeable. Otherwise, the crystal is perfect.
Height: 11.5 cm, Length: 11 cm
Weight: 765 g
The crystal comes from Brazil and is natural and unpolished.
Insight into the formation of rock crystal:
Rock crystal forms through the cooling of silicate melts. These melts contain silica (SiO₂) and other minerals. During the cooling process, the silicates crystallize and form quartz crystals.
Geological conditions: Rock crystal forms in cavities (veins, fissures, geodes) in rocks. Formation occurs under high pressure and high temperature. In these cavities, silica accumulates and begins to crystallize.
Time frame: The formation of rock crystal can take millions of years. During this time, the crystal grows slowly, layer by layer.
