It will go up a little at the end of the year. Hehe, just buy it now. I don't know how much the price of the diamond you want to buy will go up and down according to its size and color. The quality of a diamond is determined by its 4C, and has nothing to do with the brand. A good brand has a high additional price (such as advertising investment and shopping mall deduction), so its cost performance is not high. There is basically no difference in the price of diamonds, and the price of diamonds with a difference of 5%-10% is determined by the 4C of diamonds. Weight, color, clarity and cut. If you choose a wedding ring, you should pay attention to cost performance rather than recycling. Who sells wedding rings? You can choose high color and low definition. For example, if you choose D color definition VS2, you should at least choose VG, not necessarily 3EX. There is little difference between VG and 3EX, which has little influence on the fire color of diamonds. The fluorescence of diamonds is basically invisible to the naked eye. It is best to choose non-fluorescent ones. The hardness of fluorescent and non-fluorescent diamonds will be lower than that of fluorescent diamonds (of course, very small). Diamonds with strong fluorescence will fluoresce in the sun, which will affect the color of diamonds. For example, a diamond with blue fluorescence will be blue. The price with fluorescence will also be cheaper.
