Chang Jiang Gems CZ bellows pictures are for round 3.0mm, if smaller size will have more shortcoming. Because smaller size is hard to polish than bigger size. But the small size scratch also hard to see by eyes. The shinning will let people can't see the scratch.

长江宝饰CZ（立方氧化锆）的以下图片均为 3.0 毫米圆形，若尺寸更小，瑕疵会更多。因为小尺寸的抛光难度远大于大尺寸，但小尺寸的划痕肉眼也难以察觉，其光泽度足以让人忽略这些划痕。
