Diamond rings are cheap, hehe, in fact, except for the diamonds on them, others are expensive in brand and design. If you don't pay much attention to the brand, choose an ordinary brand. The most important thing is to choose the diamond set on the ring, depending on the size, purity and cutting of the diamond. You can go to see the diamond bird on the spring outside the south gate of Paris (it seems to be on the fifth floor, I can't remember clearly. Ask yourself when you get there. His family engaged in online diamond sales and opened a physical store in Xi 'an. Diamond rings are not very expensive. If you want to buy a diamond ring in the mall, it seems that all brands can bargain except Chow Tai Fook, which is sold at a real price (that is, you can't bargain). I have bought both Chow Tai Fook's diamond ring and Diamond Bird's diamond necklace, and I think the price/performance ratio is OK.
