It most likely has Pink Diamond's gem in it. Either the shattered remains should she have actually shattered her, or the intact gem which is manefesting itself in the form of Lion, and with the gem in a pocket dimension it not only makes it unable to be seen keeping it well hidden, but it is sure hard to even try and shatter it should Lion/Pink Diamond need to fight Yellow Diamond.
