neutronná
Neutronná is a rare and unique mineral discovered in the late 20th century. It is primarily composed of silicon, oxygen, and a small amount of sodium. The mineral is known for its distinctive crystal structure, which is orthorhombic. Neutronná is typically found in volcanic rocks and is often associated with other minerals such as quartz and feldspar. It is not commonly found in large quantities and is therefore considered a semi-precious stone. The mineral has a hardness of approximately 6.5 on the Mohs scale, making it relatively durable. Neutronná is also notable for its unique optical properties, which include pleochroism and double refraction. These properties make it an interesting subject for study in the fields of mineralogy and crystallography. Despite its rarity, neutronná has gained some attention in the gemstone market due to its aesthetic appeal and unique characteristics. However, its limited availability and the challenges associated with its extraction make it a relatively rare and sought-after gemstone.
