The Mark of International Gold 925
The hallmark “international gold 925” is a symbol of quality and authenticity in the jewelry industry. This mark indicates that the piece of jewelry is made from an alloy containing 92.5% pure gold. The remaining 7.5% is typically composed of other metals, such as copper or silver, which are added to increase the strength and durability of the gold.
The international gold 925 standard is recognized and accepted worldwide. It is often used in the production of high-quality jewelry, such as rings, necklaces, bracelets, and earrings. Jewelry made from international gold 925 is known for its beauty, durability, and resistance to tarnishing.
The purity of the gold in international gold 925 jewelry is typically determined by a process called assaying. Assaying involves testing the gold alloy to determine its exact composition. The results of the assay are then used to determine the karat value of the gold, which is a measure of its purity. A karat value of 24 indicates pure gold, while a karat value of 925 indicates that the gold is 92.5% pure.
International gold 925 jewelry is often more expensive than jewelry made from lower-karat gold alloys. However, the higher purity of the gold makes it a more valuable investment. International gold 925 jewelry is also more durable and less likely to tarnish or discolor over time.
If you are considering purchasing gold jewelry, it is important to look for the international gold 925 mark. This mark is a guarantee of the quality and authenticity of the gold, and it ensures that you are getting a piece of jewelry that will last for years to come.
