18 Karat Gold
“International gold 750” refers to the purity of gold, which is typically expressed in karats (K). The number 750 indicates that the alloy contains 75% gold and 25% other metals, most commonly copper. This is equivalent to 18 karats, as pure gold is 24 karats.
18 karat gold is a popular choice for jewelry because it offers a good balance of durability and malleability. It is hard enough to withstand everyday wear and tear, but still soft enough to be easily worked into intricate designs. 18 karat gold also has a warm, yellow color that is highly prized by many.
However, it is important to note that 18 karat gold is not as pure as 24 karat gold, which contains 99.9% gold. As a result, 18 karat gold is more susceptible to tarnishing and scratching.
Other Karat Values
In addition to 18 karat gold, there are several other common karat values for gold jewelry:
* 10 karat: contains 41.7% gold
* 14 karat: contains 58.3% gold
* 22 karat: contains 91.7% gold
* 24 karat: contains 99.9% gold
The higher the karat value, the more pure the gold and the softer the alloy. As a result, higher karat gold is more likely to tarnish and scratch. However, it is also more valuable.
Choosing the Right Karat Value
The best karat value for gold jewelry depends on the intended use. For example, 10 karat gold is a good choice for jewelry that will be worn every day, as it is more durable than higher karat gold. 18 karat gold is a good choice for jewelry that will be worn occasionally, as it offers a good balance of durability and beauty. 24 karat gold is the purest form of gold, but it is also the softest and most expensive. It is typically used for investment purposes or for creating very special pieces of jewelry.
