Natural diamonds are the classic choice in the world of jewellery. They stand for rarity, value and special moments. Every natural diamond has formed over millions of years deep within the earth, under enormous pressure and intense heat. It is precisely this natural origin that makes them so fascinating.
For many people, a natural diamond is the first choice – especially for jewellery meant to last a lifetime. For example, for an engagement ring, wedding rings with diamond settings, or a piece of jewellery that marks an important moment.
At 123GOLD, the focus is on selected diamonds of the highest quality. We help you find the right stone – for your jewellery, your style and your budget.
Natural diamonds form deep beneath the earth's surface, where extreme conditions act on carbon over an extraordinarily long period of time. From this process emerges a gemstone of exceptional hardness. Diamonds are the hardest natural mineral, which is why they symbolise durability, strength and eternal love.
No two natural diamonds are exactly alike – every stone has its own characteristics, for example in colour, clarity or structure. This makes natural diamonds true one-of-a-kind pieces. This uniqueness is one of the main reasons they are so highly valued in jewellery.
Natural diamonds give jewellery a special radiance. They look refined, clear and timeless. In an engagement ring, the diamond is often the centrepiece. As a solitaire it looks clear and elegant. In wedding rings, it is usually used more subtly – for example as a single stone or as a delicate setting.
Memoire rings, too, live from diamonds. Each stone can represent a moment. A year. An event. Or a shared milestone. Natural diamonds suit many designs – from simple to exclusive, from classic to modern.
The quality of a natural diamond is assessed using the 4Cs.
These criteria are internationally recognised and make diamonds comparable.
The 4Cs are:
the weight of the diamond
Value increases exponentially with carat weight, not linearly.
A 1-carat stone is significantly more expensive than two 0.5-carat stones.
the cut and brilliance
The cut determines how well the diamond reflects light.
the colour of the stone
The more colourless a white diamond, the higher its quality as a rule.
the clarity
The fewer visible natural inclusions there are, the rarer the stone.
The cut is particularly important. It determines how well the diamond reflects light. An excellent cut creates strong brilliance and beautiful fire. Colour also plays a major role. The more colourless a white diamond, the higher its quality as a rule. Clarity refers to natural inclusions. The less visible they are, the rarer the stone. At 123GOLD, natural diamonds from 0.3 ct are 3x Excellent and GIA-certified. GIA is one of the world's most recognised institutes for diamond grading. The certificate documents important quality characteristics and gives you confidence in your choice.
Natural diamonds can be an interesting tangible asset. What matters most is quality, certification, rarity and demand.
Even so, a diamond should not be viewed purely as an investment. Especially in the world of jewellery, the emotional significance is often paramount. The material value is important – but the personal meaning often makes the stone even more precious.
At 123GOLD, you will find natural diamonds with a clear focus on quality. We rely on verified stones, transparent information and personal advice. This is especially important because buying a diamond can seem complex at first glance. Carat, cut, colour, clarity and certificate must all be considered together to get a complete picture.

Not necessarily. A smaller diamond with a better cut or higher clarity can be more valuable than a larger stone of lower quality.
