You may not know it yet,

The recycling price of this diamond ring is not simply determined by the weight.

In fact, the recycling price of diamond ring is mainly determined by the 4C standard of diamond.

The so-called 4C standard is the weight of diamonds,

The color of the diamond, the clarity of the diamond and the cutting of the diamond.

And there are many brands of diamonds.

Brand will also affect the price of diamond ring to some extent.

As far as I know, the price of a random carat diamond is about100000 to 200000.

Even, there are millions and tens of millions.
