Как отличить камни: кальцит, кварц и кварцит

Friends ☺🖐 In this video, I'm sharing my observations on how to distinguish calcite from quartz, and quartz from quartzite. Be sure to leave your opinions and observations in the comments 🤗🌞 Calcite (mineral CaCO3) can be scratched with a needle, unlike quartz and quartzite. Quartzite (a mineral containing SiO2) is quartz particles "fused" under high pressure and temperature. Quartz (mineral SiO2) grows as distinct crystals or as intergrowths of crystals, and also as vein quartz. Thank you!
