I saw a diamond ring at Chow Tai Fook on Tanabata today. After 40 minutes, the vvs color I-J was cut by 3EX, and the price was reduced by 20,000 yuan 17000. Is there an understanding hero to help me see if it's worth the money? Carat weight of inlaid diamonds: 0.40 carat, color: I-J- yellowish white (rough diamonds are classified as I and J), clarity: extremely poor quality of VVS2 (rough diamonds are classified as VVS 1 and VVS2), cutting and polishing, symmetry: 3EX- very good, and diamond quality.

Retainer material: Au750- 18K gold, gold weight: 2.5g ..

Diamond ring price:

I color, VVS 1 grade, the cost price is about 9000 yuan, and the retail price of general merchants is about 14400 yuan;

I color, VVS2 grade, the cost price is about 8400 yuan, and the retail price of general merchants is about 13400 yuan;

J color, VVS 1 grade, cost price: 8 100 yuan, general retail price: 13000 yuan;

J color, VVS2 grade, the cost price is about 7600 yuan, and the general retail price is about 12 100 yuan.

Chow Tai Fook is an international brand, and the price of diamond ring is 17000 yuan, which is ok.

In addition, the diamond grading of this diamond ring adopts the grading standard of inlaid diamonds. Generally speaking, it is best to choose a diamond ring with a grading certificate of 30 points or above, because the color and clarity of the diamond are different and the price is different.
