In general, this range is reasonable. Generally, it depends on how much you lose. In general, K gold may cost 200 yuan one gram because it is not very expensive, but for them, the actual price of one gram is about 120 at most, the loss of 0. 1 gram is normal, and the value of 0. 1 gram is 10. And the salary of the revision master is worthless! Don't worry! Reasonable!

But the price here is not cheap either!

One gram of gold is 200* 1.857, and the process cost is 650.

Unfortunately, the diamond is 19, which belongs to the national quintessence diamond (all diamonds below 20 are national quintessence diamonds). There is no value preservation significance except decoration!

The color H is average, but the diamond is still white!

The clarity VVS is very good, which belongs to the extremely defective level, and the inside of the diamond is very clean!

Since you haven't given the data of diamond cutting (but such a small amount won't affect much money), I'll give it to you in the middle!

The market price of this diamond is: 1800.

Plus the profit of the merchant, it is reasonable that the whole finished product does not exceed 3380! The price of 3905 is a bit high, but it is a very profitable industry, so it doesn't matter if you like it! Unfortunately, it is 19 diamond. If it is 20 points, it will be perfect!
