I tend to believe that combining a luck stone and a protection stone is a good thing. Jade is not only a money stone, but a good luck stone. Not to mention delicate and beautiful. Onyx is a stone of strength and protection. I didn't assume that the stones would be so close in size, but they were!
They almost look like black and white earrings, but rest assured, they are light green jade green and black onyx. They compliment one another nicely.
