The difference between 3d hard gold and 999 gold

1, the purity is different, 999 gold is also called pure gold, and the purity of 3d gold is slightly worse; 2, the process is different, 999 gold is made by traditional process, and 3d gold is made by electroforming process; 3, the hardness is different, and the hardness of 3d gold is higher than that of thousands of gold. The main difference between 3d gold and 999 gold is the difference in purity. 999 gold has a high purity, also called pure gold, which means that its gold content is as high as 99.9%, which is also the highest value named after the purity of gold in the market, while the purity of 3d gold is slightly worse. In addition, their manufacturing processes are also different. 999 gold adopts traditional gold production process, and 3d gold adopts electroforming process, which is much more complicated and breaks the limitations of traditional gold. At the same time, their hardness is also very different. 3d gold is made by special technology, and its hardness is 3 ~ 4 times that of ordinary gold, with strong wear resistance, hard texture and comfortable wearing, while 999 gold is soft and easy to deform.
