A diamond with a score of 10 can directly ignore the color and clarity, because no matter how bad the clarity is and how yellow the color is, it can't be distinguished by the naked eye, because the diamond is too small, but since you bought it, I will help you calculate the cost of this pendant.

The price of diamonds fluctuates little at 10, even if it is VS F-G, that is, the price of PT950 in 1200 is 440 yuan in 1 and 420 yuan in/gram of PT990. 6 grams, that is, 670 yuan, plus a little money, so the cost comes out.

Lao Fengxiang's price is definitely not low, but since jewelry is a luxury, you also like this style when you choose to buy it, or it looks particularly noble when you wear it, so it is more expensive.

But if you buy bigger diamonds in the future, I recommend you to go to some brands that specialize in loose diamonds.

The above is my personal opinion, and I hope it can provide you with reference.
