Most silver shops will have additional conditions when they carry out trade-in business. The old silver jewelry is calculated according to the price of silver, because the recycled silver jewelry needs to be reprocessed into silver. Because silver is not a hard currency like gold, it will not be realized in the market unless it is specially used to invest in silver varieties. There are many additional conditions for exchanging old for new, which are caused by the cost of silver in the process of reprocessing and circulation.
Most brands basically do not provide silver jewelry /k gold jewelry for the old. Generally, only pure gold (that is, pure gold or thousands of pure gold) and platinum (990 or 950) can enjoy the trade-in, because these jewelry are of high purity and have recycling value. Only some jewelry that specializes in K gold can be replaced with new ones.
