Whenever you hear or read the term ‘karat’, you should start thinking in terms of how the purity of gold is measured.
So, before you go further to know the difference between the different karats of gold, it would be very important to first understand what karat stands for.
Therefore, karat is basically a unit that’s used in the measurement of gold’s purity.
That is to say, when the karatage is high, then the gold is purer. Below is all about the main differences between different karats of gold.
1) 24K gold
24K gold is the pure gold or just call it 100% gold.
That means that this type of gold is pure and no any other traces of metals can be found. It’s always tested to be 99.9 percent pure and it has a bright yellow colour.
Before you start walking to your dealer, you must know that 24K is the higher form of gold who may take advantage that you don’t know.
Of course, everything that’s pure has to be expensive. Therefore, this type of gold is more expensive than any other type of gold like 22 or 18K.
However, 24K gold is less in density as compared to the other types of gold; making it soft and pliable.
Sadly, because of that, it’s not the best for jewellery. Instead, coins and bars are the ones that are bought from this type of gold.
You can use 24K gold in the making of electronics and medical device – used for kids with ear problems. These devices improve your child’s aeration of his or her middle ear.
2) 22K gold
If you’ve gone through 24K gold and you’ve understood it well, then you’ll have no problems understanding 22K gold. Why? When you talk of 22K gold, it means that only 22 parts of it are gold while the rest of it is a compilation of other metals.
That’s also to mean, only 91.67 percent is pure gold. This type of gold is, therefore, suitable for the making of jewellery items.
The most challenging part in gold is checking gold purity. You might be asking yourself, “but where are the 8.33 percent?” Well, the 8.33 comprises of nickel, silver, zinc and other alloys.
And another question may pop up your head, “what then makes 22K gold suitable the making of jewellery?” The answer is that the addition of other metals in 22K gold makes it harder, thus making it the best for making jewellery.
Sad news though. In as much as 22K gold may be the best for jewellery, it will not be the best for diamonds or heavy jewellery.
3) 18K gold
As we go down, the quality of gold goes down by 25 per cent. So, 18K gold is just 75 percent pure. 25 percent goes to other metals like copper.
You realized that 22K gold could not make heavy studded jewellery, but with 18K gold, it’s the perfect match and it’s also cheaper compared to 22K and 24K gold.
18K gold is slightly dull in colour compared to 24K gold that is brightly yellow in colour
Identifying the 18K type of gold is much simpler. Always, you’ll notice that it’s stamped with either 18K, 18k, or 18Kt. In some cases, you may find that 18K gold has been marked with 750, 0.75.
Now you know the different types of gold and that if someone ever asks you what karat is, you’ll have something to discuss with him or her. If you’re going to buy any of these types, you also know where the prices range.
