First, the factors that affect the price of chalcedony: First, whether the chalcedony is natural. This is because the chalcedony market is full of fake chalcedony, and the value of these chalcedony is very low. Therefore, these fake chalcedony jewellery can be purchased for as little as a few dollars. The second is color. Color has always been a selling point for jewelry, and different colors give people different feelings. The third is the volume of the chalcedony. The so-called object is rare, and the chalcedony with a large volume is relatively rare, so the price is high. The fourth is the texture of chalcedony. Generally speaking, the cracks appearing in the chalcedony and the less impurities are less obvious, the higher the value; and the more uniform and fine the structure of the chalcedony, the denser the combination, the higher the quality and the higher the value. The fifth is the technique and fame of the engraving master. Some good chalcedonys have been carefully designed and carved by the famous jade carving masters, which can add a lot of artistic value. Such chalcedony carvings often cost more than 10,000 pieces. Black Oxford Shoes,Tan Oxford Shoes,Leather Oxford Shoes,Casual Oxford Shoes GDMK GROUP WEIHAI SHOES CO., LTD. , https://www.gdmkgroup.com
