International Gold Karat Meaning
Karat is a unit of measurement used to express the purity of gold. It is based on a scale of 24, with 24-karat gold being pure gold. The lower the karat number, the more alloyed the gold is with other metals, such as copper, silver, or zinc.
The international standard for gold karat is defined by the International Organization for Standardization (ISO). According to ISO 9257, the following karatages are recognized:
* 24 karat (99.9% pure gold)
* 22 karat (91.6% pure gold)
* 18 karat (75.0% pure gold)
* 14 karat (58.3% pure gold)
* 10 karat (41.7% pure gold)
* 9 karat (37.5% pure gold)
In addition to the ISO standard, some countries have their own national standards for gold karat. For example, the United Kingdom uses a system of hallmarks to indicate the karatage of gold, with the following marks being commonly used:
* 9 carat (375)
* 14 carat (585)
* 18 carat (750)
* 22 carat (916)
* 24 carat (999)
The karatage of gold is an important factor to consider when purchasing jewelry or bullion. Higher karat gold is more valuable and durable, but it is also softer and more expensive. Lower karat gold is less valuable and less durable, but it is harder and more affordable.
When choosing the right karatage for your needs, you should consider your budget, your intended use for the gold, and your personal preferences. If you are looking for an investment, higher karat gold is a good option. If you are looking for jewelry that you will wear frequently, lower karat gold may be a better choice.
