The price inside is 1/3. I think his website is quite formal and safe.
Remember, the diamond you choose must have GIA certificate.
After buying it back, go to the jewelry appraisal agency in the local or neighboring city for re-inspection. If it matches the certificate,
As mentioned above, if you pay again, there will generally be no problem.
Generally speaking, if you buy diamond rings online, these brands are better and more convenient than Zhou Shengsheng and Zhou Dasheng.
It's fast, but it's quite cost-effective. I also bought my wife's diamond ring online. But you bought this.
It's best to brush up the relevant knowledge first)
I suggest you popularize the measurement of diamonds, which is called 4C. This is very helpful to you.
We should consider the following four aspects (4C):
(1) color: colorless is the best, and the darker the tone, the worse the quality. In the color classification of colorless diamonds, the top color is D, which goes down to Z. Here we only talk about the color scale from D to J. D-G is colorless, and G-J is almost colorless. From K, there is basically no collection and wearing significance. Because diamonds will gradually turn yellow from K, when we choose diamonds, we should try to choose the color above H. Although I-J belongs to the category of near colorless, we can still detect a trace of yellowish. Colored diamond, such as red, pink, green and blue, is a treasure in diamonds, and its price is expensive. Among them, red diamonds are the most precious.
(2) Clarity: Clarity classification is based on the location, size and quantity of inclusions. The clarity grades are divided into FL, IF, VVS 1, VVS 2, VS 1, VS 2, SI 1, SI2, SI3 and P65438 from high to low.
(3-carat weight): When the other three C's are the same, the price of a diamond is directly proportional to the square of the weight, and the greater the weight, the higher the value. The weight of diamonds is measured in carats. 1 carat (carat) = 0.2g (gram). Divide one carat into 100 pieces, each piece is one point, and the 0.3 carat and 0.4 carat marked on the price tag of the mall are what we call 30 points and 40 points.
(4) Cutting: A diamond's original stone will not be noticed even if it is thrown on the road. It is cutting that gives it a second life and gives it a gorgeous fire color. Cutting refers to the geometric shape and arrangement of various valve faces of finished bare diamonds. Cutting is divided into three categories: cutting ratio, grinding and decoration. Each item has five grades, from high to low, excellent, very, good, average and poor. Generally, what we see is the standard round drill cutting. Top-cut stones can reflect light in the most perfect proportion, which is what we call three EX (excellent) cuts, but the price of this cut will be a little more expensive, because its yield is relatively low, which will be about 5% higher than that of stones without three EX cuts, but the fire color of three EX cuts is absolutely the most beautiful.

Then when you buy it, you usually need GIA certificate for loose diamonds and CMA certificate for finished diamond rings. By the way, besides normal 4C, it is also important to see if there is fluorescence.
Well, I hope it can help you after all this verbosity.
I wish you can buy your favorite diamond ring.
