1 Carat
The weight of a diamond is the most obvious factor to determine the value, but two diamonds of equal weight can have a significantly different value. This depends on the total of the 4 C’s. Bigger is not always better! The weight of a diamond is measured in carats. One carat weighs about 200 mg.

2 Clarity
Clarity stands for purity. Diamonds consist of pure carbon and this sometimes leaves traces of minerals, gases or other substances, inclusions we call this. Only very rare diamonds have no inclusions and are given the predicate ultra pure. The size and number of inclusions therefore determine the value of the diamond. Diamonds are sorted into one of the following six categories:

3 Colour
Colour stands for the colour of the diamond. Most diamonds appear to be white, but on closer inspection usually contain a colour. The more colourless the diamond, the rarer it is and therefore the more precious it is. The purest colour diamond is River, an ice-white, clear and almost colourless stone, in which the light is reflected optimally. There are also stones that naturally have a distinct colour, such as pink, champagne, green, red, blue or yellow. These diamonds are called ‘fancy colours’ and are extremely rare.

4 Cut
Cut represents the cut of the diamond. It determines how the light is reflected. A rough diamond looks very much like a pebble. You’ll probably walk right past it. The splendour of this diamond is hidden in the core and only appears after accurate cutting. The most common cut is the brilliant, this is a round variant with many facets. You can also choose an oval stone the ‘marquise’, a rectangular stone the ‘baguette’ or a square stone a ‘princess’.

The extra C of Aller Spanninga
As soon as the diamond setters of Aller Spanninga receive the diamonds, they are first sorted manually, each on the four C’s above. Possible imperfections are immediately filtered out. The diamonds that pass our quality control are then also sorted on diameter by means of a special sorting machine (a film about this on our Youtube channel).

As an Aller Spanninga fan you can be sure of the four C’s and the right diameter. The diameter is the fifth C of Aller Spanninga! This diameter is very important to us. Because if you choose for a ring with several diamonds, you want them all to be exactly the same size. That is what we go for and that is the extra C of Aller Spanninga!

Picking out diamonds?
So, just had a crash course in diamonds! Now look for the rings that suit you! With or without one or more diamonds. We offer a wide choice of rings with diamonds. Do you already know what you want? Take a look at which Aller Spanninga jeweller is near you.

In gold jewellery the gold content is indicated by carat, but what is carat gold anyway? What is the difference between the types of carat gold, such as 9, 14, 18 and 24 carats? And how can you tell how many carats of gold there is in a ring? In this blog we explain all about it, so you can make the right choice when buying gold wedding rings!

How many carats is pure gold?
The term carat in gold indicates how much pure gold there is in a piece of jewelry. In a ring there is often a stamp that indicates how much pure gold is in the ring. Pure gold is expressed in 24 carats and contains 99.99% gold. However, pure gold is very soft and therefore flexible and sensitive to wear and tear. By adding other metals, the gold is hardened, creating different gold contents and different colours. This process is also called alloying. These additives are often copper, silver or palladium. By hardening the gold, it can be better processed. Pure gold is actually too soft to make jewelry and is therefore unsuitable for rings.

What does carat say about gold?
The ‘carat gold’ is a measure of the amount of fine gold in a ring. The height of the carat indicates how much pure gold a ring contains. The proportions are as follows:

8 carats: 33.3% pure gold, indicated by 333
9 carat: 33,75% pure gold, marked with 375
14 carat: 58.5% pure gold, marked with 585
18 carat: 75.0% pure gold, marked with 750
20 carat: 83,3% pure gold, marked 833
21.6 carats: 90.0% pure gold, marked with 900
22 carats: 91,6% pure gold identified by 916
24 carat: 99.99% pure gold, marked 999
In the Netherlands the vast majority of gold rings are made of 14 carat gold, followed by rings made of 18 carat or 9 carat gold. Do you have a ring made of 8 carat gold? Then it most likely comes from Germany. In the Netherlands 8 carat new is not sold, by law it may not be sold as gold.
