Diamonds with more than 20 points and less than 50 points belong to small diamonds, which are lower and middle in price. The prices of mainland jewelry brands, including Luk Fook Jewelry, are on the high side, so it is meaningless to simply estimate the price of diamonds. H-colored diamonds with a SI clarity of 33 can be valued at more than 5,000 in Liu Fu, and as long as it does not exceed 7,000, it is considered as a reasonable price in Liu Fu. If you just ask about diamonds, in the local jewelry store in Hong Kong, the price of diamonds of about 30 carats is about 2,000 yuan. If you can bargain, you can probably start with 1500- 1700. I wonder if it helped LZ.
