Jewelry labeled as solid gold usually contains a gold alloy, not pure gold. Pure gold is too soft for durable use. Solid gold jewelry mixes pure gold with zinc and copper to create a stronger material. Therefore, while it is called ‘solid gold,’ it is actually an alloy designed for better durability.
In contrast, gold-plated or gold-filled jewelry contains a base metal covered with a thin layer of gold. Gold-plated items can wear off over time, revealing the base metal beneath. Gold-filled jewelry, however, has a thicker layer of gold, making it more durable but still not solid gold.
To spot the differences between types of gold, look for hallmarks. A stamp indicating 10K, 14K, 18K, or 24K specifies the gold purity. Checking for the mark ‘GF’ identifies gold-filled items, while ‘GP’ refers to gold-plated.
Understanding these distinctions helps you make informed choices when purchasing jewelry. In the next section, we will explore how to properly care for and maintain your gold jewelry to preserve its beauty and value.
What Does It Mean When Jewelry Is Labeled as Solid Gold?
