The term “1/20 12kt” refers to a specific type of gold jewelry or item that indicates both the gold content and the proportion of gold in the piece.
Here’s the breakdown:
1/20: This fraction indicates that 1/20th of the total weight of the item is made up of gold. This means that for every 20 parts of the item, 1 part is gold. In terms of percentage, this translates to 5% gold content.
12kt: This stands for 12 karats, which is a measure of the purity of gold. Pure gold is 24 karats, so 12 karats means that the gold is 50% pure. However, in the context of “1/20 12kt,” it indicates that the gold used in the item is 12 karat gold.
When you combine these two pieces of information, “1/20 12kt” signifies that the item is made of a material where 5% of its weight is 12 karat gold. This is common in gold-filled jewelry, where a layer of gold is mechanically bonded to a base metal, providing a more affordable alternative to solid gold while still maintaining some of its properties.
