1, platinum has the value of preservation, but it is not recommended. When platinum is recycled, the price is much better than gold. First, even if the platinum is scratched, only the metal is moved, which will not affect the volume; Second, because platinum is very rare, it is used less, so the price is higher when it is recycled, but it is more difficult to recycle. In view of the complexity of platinum melting point and hardness recovery treatment. There are many uncertain factors in the process of detecting the purity of platinum, which also makes goldsmith reluctant to recycle platinum. If the gold ornaments are not recycled, they can only go to pawn shops or sell them cheaply in the future.

2. Platinum is really difficult to process and recycle. Suppose the international price of platinum is 200 yuan per gram, but with various processing fees, the finished product is as high as 3401g. Few gold jewelry stores dare to recycle platinum, because platinum testing is more troublesome. Unlike gold K, experienced people can basically judge authenticity and purity, while platinum can't. Even if there are platinum recyclers, they can't even give half the price of platinum. In addition, platinum has many inconveniences. Due to the high melting point, most gold shops and jewelry stores do not provide resizing services. If they have no size, they have to buy other styles. In addition, platinum should also be rhodium-plated, which is similar to 18K gold with rhodium-plated surface.

1, the purity of platinum jewelry is usually 90%-95%, and the common purity of platinum jewelry is Pt900 and Pt950. According to national regulations, only jewelry with platinum content above 85% can be called platinum jewelry. Platinum jewelry is qualified in purity and will not cause skin allergy. Platinum has a natural pure white color, and the white luster is natural and pure, giving platinum jewelry a unique appearance. Even if it is worn daily, platinum always maintains a pure white luster.

2. The processing technology of silver products is better now than in the past. Generally speaking, many finished products are plated with a rare metal: rhodium. Bright and stable, not easy to fade. As long as it doesn't wear off. Generally, the old master only recognizes 99.00 or 99.90 silver goods. At first glance, it is not dazzling, but it gives people a sense of stability. But silver is unstable and easily exposed to the air.
