Отзыв о Образец необработанного минерала кальцита, отобранный Eisco Labs вручную - идеально подходит для научных классов - прибл. 1" - Экспертная обработка геологами от Mike Davis

This raw calcite mineral specimen from Eisco Labs is a real gem for any science classroom! The hand-selected piece is expertly processed by geologists, making it a reliable tool for experiments and demonstrations. At approximately 1", it's the perfect size for students to handle and examine. Plus, the beautiful natural patterns and colors will captivate anyone's attention. The only reason I didn't give it 5 stars is because it's a bit on the pricey side. But, considering the quality and how long it will last, I think it's worth the investment. Overall, this calcite specimen rocks!
