Good To Know
Why are there different carats, what does it mean, and what is the difference between red and white gold? Read on and get wiser on your gold jewelery. Not everything that glitters, it’s just gold. This is an old saying, but when you visit your local jeweler, you can be sure that what looks like gold actually is
In addition to 24 carats, Denmark primarily works with three conditions:
- 18 carat (750 per mille)
- 14 karat (585 per mille)
- 8 carat (333 per mille)
In Denmark, most jewelery is made of 14 carat gold and in rarer cases 18 carat, while a number of industrially made jewelery is also available and made in 8 carat. In addition, jewelery in this country must always be stamped with the stamp of responsibility and an indication of how much precious metal is in the jewelery.
On the other hand, gold in its purest form is extremely malleable and is the most flexible material known. In fact, a single gram of gold can be hammered out into one square meter of gold leaf, which can be made so thin that it becomes transparent.
Because pure gold is so soft, the gold is alloyed with other metals such as silver, copper and palladium to make the metal more durable so that it can be used to make jewelry.
18 carat gold is stamped 750 because 750/1000 of the alloy is pure gold.
14 carat gold is stamped 585 because 585/1000 of the alloy is pure gold.
8 carat gold is stamped 333 because 333/1000 of the alloy is pure gold.
Some countries also use 9,10,19,20 and 22 carats, but in Denmark the three above are by far the most used. However, all entries can be found in Denmark, as you can stamp freely between 333 and 999.
In return, the gold is available in various purities, which are stated in carats. The purest gold is called fine gold and is denoted 24 carats. It is the most precious, but it is not optimal for jewelry because fine gold is very soft. Therefore, a piece of fine gold jewelry will easily be exposed to dents and scratches.
Gold is a precious metal that is not attacked by atmospheric oxygen or other substances in the atmosphere, but stays shiny. One can test if a metal is gold, by exposing it to nitric acid, which attacks other metals but not gold.
Seawater contains gold, but in such small quantities that it is not worth extracting. One tonne of seawater contains between 0.1 and 0.2 milligrams.
