Hi, Ms. Monique, don't clean it. Some jade's color do changes, and I had a pink color. Its color is turning to be very ligher now. It doesn't mean it is not clean. I think it means the same with pink jade, which we also called rose jade. It is purple pink color. This kind of jade looks beautiful but color is easily changed. Generally speaking, it can not change into gree or bule color. So, there is another possibility, it is once dealt with chemical dyestuff.
