LD should stand for the abbreviation of brand, G750 stands for the metal material of 18K gold, D stands for the abbreviation of diamond, and O.09Ct stands for the weight of diamond, which is 9 points. This kind of diamond is less than 20 cents and belongs to broken diamond. Presumably LZ's diamond ring is a finished product, the color should be I-J, and the clarity VVS-SI is possible. The current international quotation for this kind of diamond is around 600 yuan -430 yuan (according to the change of clarity). Generally, the gold of a lady's ring is about 2 grams, and the gold ring of 18K, plus the service fee and appraisal fee, the packaging fee is about 5,600 yuan. The price is determined by the purchase channel. Generally, it is definitely more expensive to buy from terminal retailers, because there are many middlemen, the price tag is 3-4 times the cost, and the promotion cost of big brands is high, which may be more expensive. These added values will eventually be paid by consumers. If you want to buy affordable goods, it will be cheaper to buy them from diamond wholesalers than from shopping malls. Personally, I think the price you bought is still within a reasonable range. Since I bought it, I'm sure I like it. This is the most rare thing. As long as you like it, it's worth it ~
