3D hard gold is doped with other metals. So it's not that pure gold is worthless, so it can't be exchanged. 3D hard gold mainly sells technology.

3D hard gold thousands of gold? Using advanced hollow nano electroforming technology, the weight of jewelry of the same size is only 30% of that of ordinary thousand gold, which is lighter and more affordable; It makes ornaments that look similar in size much cheaper in price. It has low weight, light appearance and is more convenient to wear.

Extended data:

3D hard gold jewelry is made from wax mold. The wax model is exquisitely carved and meticulous, and 3D modeling can be boldly used to make it fully play in 3D space, which is very three-dimensional. Advanced space dewaxing technology is adopted, which has no solder joints and seams, and the surface morphology is smoother and more perfect.

It gives thousands of gold jewelry a brand-new visual highlight and market hotspot. Secondly, due to the improvement of hardness, the design and technology have been greatly liberated, and some exquisite and delicate styles can't be made, while the 3D hard gold method can be made, and the workmanship is more meticulous and artistic, and the problem of setting gems has been perfectly solved.
