蓝玉 is a 宝石 found within the 地下 and 洞穴 地层s of a world. They are obtained by breaking special 物块s that have noticeable blue gemstones embedded in it. They can also be extracted from 泥沙, 雪泥, or 沙漠化石 by putting them in an 提炼机. Rarely, Sapphire can be found in bulk in its own special gemstone cave, or in one that contains all of the other gems as well (besides 琥珀).
