Personally, I think the quality of Delong's diamonds is much better than others. The texture is different. People who don't know how to drill feel good because they are also paying attention to rings when they get married. After a walk around the pedestrian street, I feel that Delong's ring is of good technical color, but the price is high. Generally, 50 points are more than 50 thousand, and other brands can buy bigger ones than him. Just look at whether you pay attention to quality or appearance size.
