By buying jewellery made of gold, in addition to physical beauty, you also make a kind of financial investment.

Gold is a soft, malleable element that exists in pure, pale yellow colour in nature. This metal does not rust in the presence of air and water. Since gold has the ability to reach very small strands, it is widely used in the jewellery industry.

Of course, it is worth mentioning that this precious element is not only used for investment and use in jewellery, but also in other industries, for example, in electrical wiring or even dentistry, gold is used.

In the gold industry, too, pure gold (24 carats) is often combined with other metals to improve its strength and ductility due to its extreme softness . Copper is the most common metal in gold alloys and makes them redder in colour.

With this introduction, we invite you to read the tricks of buying gold as a profession in this article.

When is gold used for plating?

This is done when they want to reduce the final price of the jewellery. In this way, another metal is used to make jewellery, and finally, gold is plated on it. The thicker the coating, the less likely it is to clear over time.

Full gold plating

In some new jewellery, the type of gold used to make the cover is inserted on the product. A mark such as 1/20 12K GF, meaning one twentieth of the final weight of this jewellery, is 12 carat gold.

Gold surface coating

The gold layer in surface coated products is much thinner than in fully coated samples. As a result, they wear away from the metal surface much sooner and disappear.
