Well, darling, 777 is not a hallmark in gold. It's actually a common number associated with luck and gambling in some cultures. If you're looking for a hallmark in gold, you might want to check for stamps like 24K, 18K, or 14K to indicate the purity of the gold. But hey, maybe 777 will bring you some good fortune instead!

In the context of gold hallmarking, the number 777 typically refers to the purity of the gold, indicating that it is 77.7% pure gold. This purity level is commonly associated with 18 karat gold, which is a popular choice for jewelry due to its balance of durability and value. Gold hallmarks serve as a guarantee of the metal's quality and authenticity, providing important information to consumers and industry professionals.
The value of gold is not determined by a hallmark but the amount of gold within the jewelry. There should be another symbol showing 10K, 14K, 18K, or 24K on the item. These number represent the amount of gold in carets of the item and by law they have to be listed. If it doesn't have this it is most likely not gold but a base metal with a gold overlay. If it is the value is nil. Take your item to a jeweler to determine it's value.
