Matters needing attention and key points of gold necklace:

The location of solder joints is often the most prone to problems. If there are fewer solder joints, there won't be so many problems in the process of wearing. For example, many people like Thai chains with many solder joints, but the repair rate of this necklace is also relatively high. Merchants always use solder paste when making gold jewelry, which is very common, but the use of solder paste leads to the decrease of the overall gold content of jewelry.

The actual gold content may not be as high as described by the merchant. The amount of welding solder directly determines the overall purity and value of jewelry. If you want a gold necklace with high purity and high value, please choose a regular manufacturer or a gold necklace with few or no welding points to ensure the value of the necklace.
