The brand is meaningful. When the brand is big, it mainly increases the added value of the brand, and the price will be higher, but relatively speaking, the after-sales will be better, because the brand is still very important! But the brand is not too important, generally as long as it is a formal and legal store.

18K gold, the price is around 194. Rings of more than one gram and two grams can be made in 600 yuan, including the processing fee. Diamond 0.0 1CT is 1, 1 carat = 0.2g = 100, and diamonds below 20 are broken diamonds, which are mainly decorative and have no function of preserving value. A diamond of 1 is almost the same as a diamond of 50 yuan. The price of 1380 is a bit high. If you buy 10 cent diamonds at this price, it is still reasonable:)
