Gold is a noble metal of the highest standard. This is stainless metal. Gold is practically not destroyed by chemical reagents, as well as by contact with the environment, regardless of temperature. It does not change either under the influence of heat, or under the influence of humidity, or under the influence of corrosive agents contained in the air.
The mesmerizing golden color and relative rarity of gold have made it the most valuable and sought-after metal for ornamental purposes.
Gold is an extremely dense metal. But it is also the most malleable metal. At certain temperatures and mechanical stress, it can undergo irreversible deformation. And the most flexible. It can be pulled out to the thinnest thread. But it is too fragile and flexible to be used only in its pure form in jewelry. Therefore, gold is mixed with other metals, which gives it greater strength.
In colored gold products, depending on the desired shade, the alloy contains gold, silver and copper. Changing the proportion of these two metals allows you to get the desired shade. With a higher copper content - more red. A higher silver content results in a more yellow tint.
Filigree products, like all objects of art and luxury, use an alloy of copper and silver.
In Portugal, the percentage of gold in the alloy per kilogram is 800 g for pure gold (80%) and 200 g for the rest of the alloy (20%). This is known as 19.2 carat gold.
There are also cases where the percentage of gold in the alloy is 75% by 25% (the so-called 18-karat gold).
