3D hard gold is gold jewelry made by electroplating. Currently, there are two types of electroforming in the industry, cyanide electroforming and cyanide-free electroforming. Cyanide means that the electroplating solution contains cyanide. Chemicals, cyanide-free means no cyanide. Patented cyanide-free electroforming technology uses gold sulfite salt to replace ordinary hard gold. Products use highly toxic electroforming liquids such as gold potassium cyanide. The entire production process and products do not contain cyanide, lead, mercury, cadmium, hexavalent chromium, Nickel, arsenic, thallium, cobalt and other harmful elements.

Gold is the elemental form of the chemical element gold (Au). It is a soft, golden, corrosion-resistant precious metal. Gold is one of the rarer, more precious and highly valued metals. Internationally, gold is generally measured in ounces. In ancient China, "liang" was used as the unit of gold. It is a very important metal. It is not only a special currency used for reserves and investment, but also an important material in the jewelry industry, electronics industry, modern communications, aerospace and aviation industries and other sectors.
