Laboratory diamonds are real diamonds created using a highly technological process. The chemical and physical processes that take place in the formation and composition of natural diamonds are produced in the laboratory.

Laboratory diamonds are not extracted from the ground and therefore do not interfere with natural processes. The production of laboratory diamonds uses significantly less energy than the mining process. In addition, they are conflict-free, which also makes them socially ethical.

HPHT is more expensive and less energy efficient. In this thermodynamic process, a diamond seed is embedded in pure carbon and then subjected to intense pressure and heat. The carbon attaches to the diamond seed in 14 different directions, forming a rough diamond with a complex cuboctahedron shape.

CVD is a more economical and sustainable process that converts carbon-containing gases into plasma in vacuum chambers with less energy. The kinetics allow the carbon atoms in the chamber to build up on the diamond seed in a single vertical direction, giving the rough diamond a cleaner square shape.

A lab grown diamond takes about a month to grow. It is then cut and polished before being sold as a loose diamond or set in fine jewelry.

Not all lab grown diamonds are created equal. Many lab-grown diamonds are made in manufacturing facilities that use fossil fuels as an energy source. Your carbon footprint can be as big as that of a conventional mine. However, the DIAVON MANUFACTURED DIAMONDS come from our emission-free foundry and are sustainably cultivated.

The physical, chemical and optical properties of a so-called “synthetic” diamond and a natural diamond are identical. “Synthetic” diamonds are not “fake” or “artificial” diamonds. But on the contrary; they are also real diamonds created in the laboratory. Only their origin distinguishes them from each other.

"Synthetic" diamonds are not an investment and have no resale value - so the common opinion. However, they have the same qualitative properties as mine diamonds. They are real, valuable diamonds.

While it may seem very advanced and modern to be able to create a diamond in a laboratory using state-of-the-art technology, diamonds were actually first created in the 1940s. But it wasn't until the 1970's that lab grown diamonds of gem quality could be produced. Initially, laboratory diamonds were primarily used for industrial purposes. As the demand for man-made diamonds increased, they were increasingly used within the jewelry industry over time.

You cannot tell a lab grown diamond and a mined diamond apart with the naked eye. It takes special laboratory equipment to tell the difference because lab grown diamonds have the identical optical, physical and chemical properties as well as the same crystal structure as mined diamonds - the only difference is their origin.

By replicating the growth process that normally takes millions of years in nature, MANUFAKTURDIAMANTEN are identical to traditionally mined stones, but without the negative social and environmental impacts. A MANUFAKTURDIAMANT® is made from a kind of “carbon seed” using the CVD process (Chemical Vapor Deposition). This carbon seed is placed in a sealed chamber filled with, among other things, a carbon-rich gas such as methane, and heated to around 800 degrees Celsius. The gases are ionized into a plasma using technology similar to that of microwaves. The ionization breaks the molecular bonds in the gases. Under high temperature and enormous pressure, the carbon atoms gradually attach themselves to the crystal lattice of the diamond and enlarge it into a rough diamond. Our MANUFAKTURDIAMANTEN are produced in a high-tech laboratory such as that of the Diamond Foundry, find out more here .

Yes, our MANUFAKTURDIAMANTEN have the same chemical, physical and optical properties as mined diamonds. Even the random inclusions that make mined diamonds so unique also form during the manufacturing process of a MANUFAKTURDIAMANT.

MANUFACTURED DIAMONDS are real diamonds that are identical in their chemical composition to mined diamonds. Not even an experienced gemologist will be able to distinguish a lab grown diamond from a mined diamond. MANUFACTORY DIAMONDS are valued according to the same quality standards as mine diamonds and are certified by all established gemological laboratories.

Yes, GIA, HRD and IGI grade all lab grown diamonds. Our MANUFACTURE DIAMONDS over 0.5 ct are delivered with one of these certificates. At DIAVON we mainly use a GIA or IGI report. On request, we can also get your dream diamond with another certificate of your choice.

Yes, just like mined diamonds, our MANUFACTURED DIAMONDS receive a certificate from one of the established gemmological laboratories, such as IGI or GIA.

Yes, just like natural diamonds, we offer MANUFACTORY DIAMONDS in numerous fancy shapes and fancy colors. The sizes for our MANUFACTORY DIAMONDS start at 0.005 ct and are available up to around 10 ct. Our portfolio includes more than 50 different diamond cuts. In addition, we can realize further individual wishes in cooperation with our grinder from Idar-Oberstein.

The true value of a diamond goes far beyond its material value - this is one of our guiding principles, which is firmly anchored in our beliefs. Diamonds are a unique and incredibly emotional product. In our opinion, value is the result of appreciation. At DIAVON we see the value of diamonds beyond rarity and resale value. Sustainability in ecological and social terms, as well as a transparent value chain that guarantees absolute traceability, play just as important a role in the value of a diamond as its uniqueness. Our MANUFACTORY DIAMONDS represent real added value for people and nature.

We are certain that the appreciation for the work along the entire value chain and the responsibility that we bear towards nature with every stone alone justify the value and thus the price.

Laboratory diamonds are not extracted from the ground and therefore do not interfere with the natural process. The production of laboratory diamonds uses significantly less energy than mining them. In addition, they are conflict-free, which also makes them socially ethical.

Our MANUFACTURED DIAMONDS are created using state-of-the-art technology that replicates natural growing conditions in a zero-emission factory like the Diamond Foundry. The result is diamonds that are optically, chemically and physically identical to mine diamonds, without the ill effects of mining.

The tissue paper and shipping boxes we use are made from FSC®-certified paper and cardboard and recycled materials. The FSC® label guarantees, among other things, responsible management of the forest by only felling as many trees as the forest itself can reproduce. When selecting the jewelry bags, for example, we also made sure that only ecological and Fairtrade-certified cotton was used for the production.
