Gold purity refers to the measure of how much pure gold is present in an alloy. It is typically expressed in karats (K) or as a percentage of pure gold in the alloy. For instance, 18K gold is 75% pure gold, while 14K gold is 58.3% pure gold. Determining the purity of gold is essential to assess its value and ensure its authenticity.
Checking gold purity offers several benefits. It helps identify the true value of gold items and protects against fraud or counterfeiting. Additionally, it ensures that the gold meets the required standards for specific applications, such as jewelry, electronics, or investments. Historically, gold purity has been a critical factor in international trade and currency systems.
