chinatown wholesale costume jewelry Although the golden gold is a member of the platinum, it is strictly different from platinum: first, the seal of the golden ingredients is "PD"; and the printed composition of platinum is "PT", general signs: PT950, PT900; second, the gold gold of the golden gold; The price is lower than platinum; the third is that the proportion of gold is lighter than platinum. The operators not only do not introduce the above knowledge when they are sold, they use platinum and golden color to be very similar (all silver -white, the appearance is beautiful), and the seal "PD" and "PT" are very similar.

The purity of is also very suitable for the skin and does not cause skin allergies.
It gold, a member of the platinum, elemental symbol PD, similar to platinum, silver -white metal luster, bright color. The gravity is 12, which is lighter than platinum, and strong ductility. The melting point is 1555 ° C, and the hardness is 4-4.5, which is slightly harder than platinum. The chemical properties are relatively stable, insoluble in organic acid, cold sulfuric acid, or hydrochloric acid, but soluble in nitric acid and king water, which is not prone to oxidation and losing luster in normal conditions.
This gold has excellent physical and chemical properties, high temperature resistance, corrosion resistance, abrasion resistance and strong stretchability. In terms of purity, scarcity and durability, it can be replaced with platinum, regardless of whether It is the most ideal material to make jewelry or inlaid gemstone alone.
The platinum
symbol PT, silver gray-white, a proportion of 21.35, melting point 170 ° C, Moh's hardness 4-4.5 degrees, stable chemical properties, except for king water, is not corroded by acid and alkali corrosion, except for king water corrosion.

Although the colors and appearance were close, the fate was very different. Platinum, as a sought after object, has risen all the way. At that time, the name of gold was not obtained at that time. It was an authentic supporting role. It was mainly used as the synthetic component of other metal jewelry, such as plating a layer of 钯 outside 18K gold or silver jewelry. In recent years, as platinum has raised jewelry consumption thresholds higher and higher, some jewelry manufacturers are committed to studying gold technology and launched pure gold jewelry with a content of more than 900 ‰. The launch of the gold jewelry has increasingly attracted the attention of fashion people. These two types of gold jewelry are naturally white, shiny, pleasing to the eye, and they do not feel the obvious difference between the two. There are endless streams of distributors from all over the world. A guest from Ningbo said that the demand for consumers in Jiangsu and Zhejiang is growing, and his business is getting bigger and bigger.

Relevant sources of the Municipal Gold Jewelry Jewelry Industry Association said that generally there is no way to distinguish the gold and platinum jewelry with experience and superficial observation. Today, the standardized merchants will load Ming jewelery materials on the gold jewelry signs. Among them, the metal code of the golden gold is PD, and the platinum code is PT.

After 20 minutes, rinse salt and nitric acid with water. After drying, look at the side. If there is no change, it will have a color of about 99%; if there is a slightly acidic trace, it will have a color of about 95%; if the nitric acid traces are large, it will be about 80-90%; When the layer becomes gray, it has a color of about 70%; if all the residues disappear, it is a fake platinum.
