Hi, I just bought this huge rock of some kind of Stars... The guy called them Vietnams Stars. Someone else said that's not what they are... I know I have 2 other kinds that are more comman & pink& green & brown & white. This is the first time I have seen this kind... They are laced with a different kind of green on the inside with a hint of blue. The other side with a brownish color. The color changes with the flow of the water.
