To be considered as gold, a material must contain more than fifty percent pure gold. That’s why it’s usually about 14 carat gold, or 585 gold. The number of carats determines the value of gold.
The carat value of gold and 585 gold
The value of the gold is expressed in carats and usually appears on the piece concerned.
Carat is the mass unit of precious metals. Its abbreviation is CT or K. It serves in particular to express the gold content. One carat is equivalent to 1/24th of pure gold. The purest gold is 24-carat gold.
8-carat gold contains 33.3 per cent pure gold, 12-carat gold is 50 per cent pure, 14-carat gold contains 58.5 per cent gold, 18k gold price per gram contains 75 per cent gold, 20-carat gold contains 83.3% gold, 21-carat gold contains 87.5% gold, 22-carat gold contains 91.6% gold, 24-carat gold contains 99.9% gold. The higher the carat number, the more pure gold the material contains.
The carat is a unit that designates the authenticity and purity of gold. One of the most popular gold grades is 14 carats, also known as 585 gold. The purity of gold is measured in carats. The more karats, the more pure gold. And the more gold in gold, the higher the price.
The success of 585 gold
The number of carats is often accompanied by a number intended to explain the quality. 14-carat gold is thus 585 gold, 18k gold price per gram 750, 20-carat gold 833, 21-carat gold 875, 21 gold, 6-carat gold 900, 22-carat gold 916, 18k gold price per gram, and 24-carat gold 999. 24-carat gold is considered like pure gold. The gold content is displayed via a punch, which differs according to the number of carats. The gold 585 is the most popular content, hence the frequent question of the value of gold. The content is indicated by a proportion on a 100 or 1000 basis.
Test of the purity of gold and gold 585
Gold being a precious and expensive metal, it is important to check purity and authenticity. The purity of gold can be verified in different ways. Gold can be tested through the application of a solution on a recent small dent. This solution consists of a combination of nitric acid and hydrochloric acid.
In order to determine the value of gold, one must know the gold content and the weight. The weight of the gold must correspond to the gold content indicated on the part concerned. Totally pure gold has a high weight and is perceived to be quite heavy. The weight of gold is 19.33 g / cm³.
To weigh the gold correctly, the professional jeweler uses a calibrated scale that allows a high precision measurement. The calibrated scale can be identified by the stickers on its side, including that of Verispect (in the Netherlands), which ensures compliance with the metrology law. When weighing, a professional and recognized jeweler will allow the customer to see the weight displayed on the scale. The weight can also be verified using the Archimedes test, immersing the gold in water and calculating its weight based on the displaced volume.
585 gold and gold hallmark
Pure gold has a typical yellow color and has a punch. The punch is affixed to the gold to guarantee the prescribed content. This also applies to 585 gold. The purity of gold is marked by the punch. Marking was done in the past with a tool called punch itself. Nowadays, it is laser. The reproduction of the punch usually takes the encrypted content with a sign. This sign, which differs according to time and region, is for example also important for determining the value of vintage rings.
The price of gold per gram is an important factor when selling gold. It depends on the gold content expressed in carats. There is also a difference between directly usable gold bars and gold scrap. Gold debris or old gold must first be reprocessed before reuse, resulting in costs and loss of fusion.
The alloy determines the properties and value of gold. The White Gold alliances are for example made of an alloy. The choice of mixing gold with another metal reduces its value, but also its fragility. Gold becomes easier to use for most applications. The gold grade 585, meanwhile, is well suited to jewelry.
In addition, the price of gold is also influenced by fluctuations in the price of the yellow metal. The world price of gold is constantly changing, and the price of gold can always vary. We must follow it closely. Some jewelers also charge additional costs that they have to bear.
