A compromise between a high content of precious metal and good physical characteristics is 585 gold, which is a guarantee of the durability of jewelry and its high value.
What does gold grade 585 mean?
Gold is characterized by softness, so other metals are added to alloys to create products from it. Additives strengthen it, change the shade and smooth the surface. The composition of the precious metal in the alloy determines the assay of the jewel.
In many countries of the world, including Ukraine, there is a metric system that characterizes the number of parts of a noble material in 1000 units of alloy.
All products that enter the jewelry market are marked with a stamp that determines which part of the alloy the precious metal is. If there is no sample, it means that it is an illegally imported fake of dubious quality or an artisanal product.
The jewelry mark informs buyers about the ratio of the weight of the precious metal in the alloy to the total weight of the alloy. The higher the test, the higher the content of pure metal in the alloy. The higher its percentage in a given sample, the higher its value and value.
A sample of a precious metal is always marked with three numbers that show how much of it is in the sample. Since the numbers are ppm, the sample is translated into thousandths of a gram.
There is no real pure gold. The 999 sample is considered the highest. Its alloy contains 99.9% gold, 24 carats. It is sold in ingots of 2, 5, 10, 25, 50 g and in coins.
Gold 585 is an alloy containing 58.5% pure gold.
The rest are impurities of other metal alloys that give it strength.
What does 585 proof gold mean in the world and in Ukraine?

585 and 333 tests of gold: what they mean and how they differ
It is difficult for a simple buyer, who is not a jeweler, to distinguish jewelry made of gold 585 from 333 by appearance, if he does not know how much pure gold is in 585.
The cost of the same models made of precious metal of different alloys is different.
Jewelry made of 585 gold is jewelry that contains more pure gold, so the price of earrings or a chain will be higher than similar products of 333.
Another difference between 585 and 333 gold is hardness and durability. Products with the 333 stamp have high strength and resistance to damage and scratches. But if they are not used for a long time, they darken and lose their shine. The 585th sample is gold, any darkening and contamination from the surface of which can be easily removed with a special soft cloth. Jewelry made of it is particularly strong, which is more appreciated by buyers.
What does 585 proof gold of different colors mean?

Metal of a different color is either more expensive or worse in quality. This explains the fact why it is less popular in our country than in the countries of the European Union.
