It is better to customize the diamond ring. The quality of diamonds has little to do with the brand, but is closely related to the grade of diamonds. The same level of diamonds, the brand is much more expensive than customization. When buying a diamond ring, it is very important to distinguish the specific grade of the diamond. Basically, well-known jewelry brands can buy diamond rings, but it is not worth buying, because the cost performance is very low, the brand value is high, and the profit rate is high, all of which are earned for nothing. It is best to have a GIA certificate when buying diamonds, so that diamonds are more reliable. But if the score is below 30, there is no GIA certificate. At present, many professional customizations have good cost performance, and the actual value is equivalent to that of big brands. For example, the diamonds of Shenzhen South Diamond Starlight Jewelry Co., Ltd. are good, with certificate certification. Diamonds are directly sold to end consumers through e-commerce mode, which reduces the sales cost and is much cheaper than some brands on the market.
