1, 18K gold, weighing about 2.5g, 200 yuan per gram, and gold is worth 500 yuan.

2, the broken diamond is about 8% to 1 min. On average, 25 pieces count as 20 points. If the SI-level H color is used, it will be around 600 yuan.

3. Manual cost 100 yuan, plus inlay about 100 yuan.

The total cost is around 1300. Of course, this is the price reached by experts. If it is sold in a gold shop, it is usually X4, which gives customers a discount. It's normal, too, because gold shops press goods, artificial water and electricity, shopping malls commission and so on.
