The World of Gold Jewellery

Gold precious metal

Gold has been used for over 6000 years to create jewellery. Because of the different types of this precious metal, there is always a type of gold that fits the current trends. A big trend for 2022 for example will be yellow gold.

Types of Gold

The different types of gold are a combination of pure gold with another metal to get the right colors. Yellow gold is often mixed with copper, zinc or silver. White gold, for example, is a composition between gold and a white metal, this can be platinum, palladium or nickel. It’s what gives white gold jewellery its silver colour.  Rose gold is mixed with copper, which gives it its pink colour. These are the basic colors of gold as many of us know them. However, based on compositions with other materials, other colors can also be created like black gold.

Measuring the Purity of Gold in Carats

Gold is measured in carats. The higher the carat, the purer the gold. The purest form of gold is called 24-carat. This consists of almost 100% of this precious metal.  It has a yellow warm glow, and has not been alloyed with any other metals.  Nowadays it’s not really used in jewellery anymore, as it easily deforms. Other metals are added to make it stronger.

In the collection of byJacky you will find many pieces made from 18 and 14 carat gold, which consists of 75% and 58.5% pure gold. In the Netherlands, 8 and 9 carat gold are no longer considered real gold, because they don’t contain enough of a percentage of gold.

Calculating Your Gold Percentage

There is a simple way to calculate the percentage of gold you are wearing. Simply divide your number of carats by 24 (as that’s when gold in its purest form) and multiply it by 100. This method is used because carat stands for 1/24th part pure gold. For example, if your bracelet is made of 14 carat gold, simply divide it by 24 and then multiply it by 100, which means your bracelet is made of 58% gold.
