1, the setting cost of jadeite and other bare stone jewels is calculated in the same way. First of all, what material is used for setting? The most common is 18K gold diamond. In the wholesale market in Guangzhou, the price of 18K gold changes with the change of international quotation every day, and recently it basically fluctuates up and down per gram of 330 yuan. The diamonds used for inlay are basically broken diamonds, regardless of grade. A 3cm diamond costs 67 yuan, and a 5cm diamond costs 13 yuan, which is almost the same as the normal price. There are also labor costs. The price of ring pendants in common styles ranges from 120 to 150 yuan, and the more complicated ones are 200 yuan. As for silver inlaid zircon, silver inlaid Mo three diamonds and so on, the price is much cheaper, the labor cost is a few dollars, and silver is also a few dollars a gram.

3. The jadeite original stone infers the quality of the internal jadeite according to its surface characteristics, and judges the price of the jadeite original stone, that is, four words, water, color and crack. The price of jadeite rough stone is gambling, and the price of rough stone is also influenced by subjective factors. Only those common water parts are weighed and sold, and the owner of high-quality jade parts will inevitably choose to process them and sell them back to their original state.
