18K gold is an alloy composed of gold and other precious metals. 18K gold can only be called 18K gold if its gold content reaches at least 75%, so it is definitely not as good as pure gold in terms of purity. If you want to make the recovery value of 18K gold higher, you can get a higher recovery by avoiding these points.
There are no diamonds.
Because the hardness of gold is relatively soft, it is basically impossible to set diamonds and precious stones. With the appearance of 18K gold, there is a kind of gold that can be inlaid with precious stones. Although the purity of gold is not up to standard, it is already "18K golden" with the same color as pure gold. However, 18K gold can be inlaid with gems, which leads to the fact that the price of 18K gold cannot be sold by grams, because diamonds are also expensive. But as we all know, gold keeps its value, but diamonds don't. When you recycle 18K gold, you will find that 18K gold is worthless.
No IP
In addition, don't buy IP-style 18K gold ornaments, because IP-style 18K gold often requires some licensing fees, such as Super IP Poké mon, Disney, Marvel Comics and Ice Shield. If the cost of these styles is high, they will be equally distributed to each commodity, resulting in expensive purchase and cheap recycling.
No brand.
When buying 18K gold, never buy luxury jewelry brands, because luxury jewelry brands will charge high brand fees. There is little difference between 18K gold styles. Ordinary jewelry brands may sell it as 100, while luxury jewelry brands may sell it as1w. It is also for this reason that it is expensive to buy and cheap to recycle.
