Diamonds have nothing to do with brands, but the value of loose diamonds. However, the diamonds in shopping malls or well-known shops have many circulation links, complicated processing procedures and large brand added value, and the price at the time of repurchase is not as good as expected, which makes investors suffer a "boring loss". If you buy diamonds for the purpose of increasing investment, it is best to choose bare diamonds or brand diamond rings, with large carats as the best, especially 1 carat or even more than 3 carats, which has a high preservation rate. In addition, due to the lack of repurchase channels, even the cost price of diamonds equivalent to 30% of the selling price is difficult to achieve in China. Usually jewelry stores only buy back gold, not diamonds, while pawn shops often buy diamonds at a price of only 10- 20% of its selling price. If you have to buy a diamond ring for others to see, buy the popular Mosan diamond. Although it is cultivated artificially, it has the same physical and optical characteristics as natural diamonds, and its hardness is second only to natural diamonds, far exceeding any other gems. Its appearance remains unchanged, and its price is only110 of natural diamonds. It's not a pity to lose it. There are plenty on Taobao. If you have to buy natural products, you have to spend a lot of money to buy more than 1 carat, and at least 40 thousand won't be much money in the future.
