Diamonds at 123GOLD

Diamonds are among the most special gemstones in the world of jewellery. They stand for love, durability and timeless elegance. At 123GOLD, the focus is on selected diamonds of the highest quality.

Every diamond has its own character. No stone is like another, and that is exactly what makes diamond jewellery so personal. The effect is created by the interplay of cut, colour, clarity and carat weight. These features are internationally known as the 4Cs and determine the quality and value of a diamond.

Diamonds in the world of jewellery

A diamond brings light, depth and brilliance to a piece of jewellery. Even a small stone can completely change the effect of a ring.

The diamond is particularly popular as a solitaire, i.e. as a single main stone, for example in a classic engagement ring. But it is also very popular as a fine setting, for example in wedding rings, memoire rings or pieces of jewellery with several diamonds.

For your piece of jewellery to look harmonious, it is not only the size that matters. Cut, colour and clarity also play a major role.

Diamonds in the world of jewellery

The 4Cs explained briefly

The quality of a diamond is assessed using the 4Cs. They help you to compare diamonds better.

1

Carat – the carat weight

Carat describes the weight of the diamond. The higher the carat weight, the larger the stone appears. However, the value does not depend solely on the size.

2

Cut – the cut

The cut determines the brilliance, i.e. how strongly a diamond sparkles. A very good cut reflects the light optimally back to the eye.

3

Colour – the colour

For white diamonds, the rule is: the more colourless the stone, the more valuable it usually is. Very light diamonds appear particularly clear and brilliant.

4

Clarity – the clarity

Clarity describes whether a diamond has natural inclusions. Many of these are hardly visible to the naked eye. The purer the stone, the rarer it is.

Why certificates are important

A certificate makes the quality of a diamond transparent, it is like an identity card for the stone.

The following important features are documented:


  1. Carat weight
  2. Colour
  3. Clarity
  4. Cut
  5. Dimensions
  6. Certificate number

Certificates provide security, make diamonds comparable and help you to make a conscious decision.

Recognised testing institutes such as GIA or IGI assess diamonds according to international standards.

At 123GOLD, diamonds from 0.3 ct are certified and 3x Excellent.

Natural diamonds

Natural diamonds are formed over millions of years deep within the earth. They stand for rarity, tradition and lasting value. Every natural diamond is a true one-off. This makes it particularly interesting for pieces of jewellery with lasting significance, such as engagement rings, wedding rings or special gifts.

Lab grown diamonds in brief

Lab grown diamonds are real diamonds. However, they are not formed in the earth, but in the laboratory. In terms of appearance, chemistry and physics, they are identical to natural diamonds. The most important difference is their origin. Lab grown diamonds are less expensive than comparable natural diamonds, which means that larger stones or higher qualities are possible for the same budget.

Ik ben goed en vriendelijk geholpen. We hebben meerdere opties bekeken zodat ik goed wist wat mijn keuze was. Ik vond beide medewerkers erg vriendelijk. Afspraken maken ging makkelijk. Ik ben heel tevreden met mijn ring.

Mooie ringen en aardig geholpen! Echter beetje apart als er 1 ring een halve maat groter gemaakt moet worden dat daar extra voor moet worden betaald. Verder redelijke juwelier. Personeel okay!

Wij kwamen terecht hier in A’dam voor trouwringen. Heel goed geholpen door Narek. Hij wist veel te vertellen over de achtergrond van bepaalde ringen en heeft heel goed geluisterd naar onze wensen. Super blij met beide trouwringen waarvan één zelf ontworpen is.
Ik raad deze zaak zeker aan!
