红玉 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 red 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, Rubies 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).
Like all other gems, Rubies can be placed on blocks. They cannot be reverted back into their 石块 version once mined.
