Synthetic diamonds are stones grown in a laboratory, optical chemical and physical properties are difficult to distinguish from natural diamonds. The 4 C's are determined like those of naturally grown diamond. So, contrary to diamond imitations such as zirconia or synthetic moissanite in inexpensive jewellery, lab-grown diamonds are also 100% carbon and have the same hardness. However, the much softer zirconia stones are artificially produced ice crystals made of zirconium oxide.

The round or brilliant cut is considered the classic and also most popular diamond shape.
We offer diamonds in all sizes and qualities, also precisely calibrated according to diameter or weight.
The diameters vary on average with 0.05 - 0.1 mm.
We have specialised in the colours D-G (Top Wesselton) and the purity VS and SI.
Our delivery time is usually 1-2 working days.
The fancy cuts include the oval, marquise, drop and heart cuts derived from the brilliant cut. The radiant and princess cuts are among the newer fancy cuts.
The emerald and baguette cuts belong to the classic staircase cuts.
Why do I need a certificate when buying a diamond?
What do I have to consider when buying a certified diamond?
How do I know if the diamond and the certificate belong together?
The diamonds have a laser inscription in the diamond's roundel. This is only visible under 20x magnification with a trained eye. However, the inscription clearly assigns the respective certificate to the diamond.
Among the white diamonds, the colours D - G are most in demand. When the colour concentration is low due to the influence of nature, diamonds have less value. Only as soon as there is a high percentage of colour in the diamond again, they are popular again and there is an increase in value. This is the case with the colour scale for diamonds when the colour is thinner than the Z colour.
The so-called fancy diamonds, where the colours in the diamond are all of natural origin, are traded in unbelievably high prices. Especially the pink diamonds fetch the highest prices. This is because pink and blue diamonds are very rare. Even of the ruby diamonds, only over 10 carats are known in the world.In our colour treated diamonds, the colour is integrated into the diamond through an identical imitation of the natural conditions. The technique used for this is called HPHT (High Pressure, High Temperature). Incidentally, this is the same technique that is used for the production of artificial diamonds.
The coloured diamonds that occur in nature are created by adding the following to the pure carbon:
In fact, synthetic diamonds can be produced in the laboratory since 1956.
Especially for industry, they are indispensable, because natural diamonds cover less than 2% of the demand for industrial use. In the meantime, CREATED DIAMOND is also available in excellent jewellery quality.
This development is welcomed by most people from many aspects, as natural diamonds are becoming rarer, old deposits are running out and hardly any new mines are being developed.
Since natural diamonds are often mined under poor working conditions and unbelievable energy expenditure, more and more jewellery manufacturers, such as the multinational Pandora, are advertising that they will do without natural diamonds from now on. In May 2021, it was announced that only synthetic diamonds would be processed. They are even somewhat cheaper, but have the same characteristics as natural diamonds. Diamonds are not only for eternity, but also for everyone, explained company boss Alexander Lacik. Stars like Leonardo Di Caprio advertise these ethically pure and resource-saving stones.
So there is a spirit of optimism in the industry. Although the use of CREATED DIAMOND in jewellery production is currently still low when compared to the overall market, if one looks at the forecasts, there is a chance that the artificially produced diamond will overtake the natural gemstone in a few years.
Synthetic diamonds are manufactured using two different methods - CVD and HPHT.
Distinguishing between synthetic and natural diamonds
Gemological institutes also issue certificates for synthetic stones, which are marked with a laser engraving on the rondiste just like natural diamonds. The recognition of cut synthetic diamonds is not possible without examination in the laboratory.
By measuring the absorption spectrum in the infrared range, for example, the absence of nitrogen can be detected. Only 2% of the diamonds grown in nature do not have nitrogen.
In addition, devices such as the Diamond View can be used to check the distribution of UV fluorescence characteristic of HPHT syntheses.
