我猜你说的是那种来有源方形圈的砖块吧~叫做环石砖~
Circle Stone Brick is yet another variant of a Stone Brick. It can only be obtained in Creative mode, as it is not generated naturally and is not craftable. Once proced in Creative mode, it can be used to craft other blocks in the same way that Cracked and Mossy Stone Brick can.
从维基上摘的。翻译过来就是：环石砖是另一种石砖。只能在创造模式中获得，既不在自然界中生成也不能合成它。在创造模式下获得后，它的合成功能与裂石砖和苔石砖相同~
所以说只有在创造模式中才有啦~
