The diamonds and stones used in our collections "Linea Verde" are real diamonds produced in a laboratory. They are identical to natural (mined) diamonds and share the same chemical characteristics.
Linea Verde
Our laboratory (culture) gems are:
- 100% optically
- 100% physically
- 100% chemically
- 100% identical to a mine stone.
There are two methods of reproducing the natural conditions in which diamonds are formed :
HPHT : A technique similar to that found in nature called "High Pressure, High Temperature" or HPHT. It consists of exposing graphite made of pure carbon to high heat and pressure.
CVD: The second method is called "chemical vapor deposition" or CVD. The process starts by placing a piece of diamond in a pressurisation chamber, where it is treated with a natural gas. As the gas heats up, pieces of carbon are deposited on the diamond and adhere to it.
What are the benefits ?
Laboratory diamonds are easily and transparently traceable. At AGUAdeORO, we know in which laboratory our cultured stones are produced and from which mines the gold is extracted to create the jewellery. Opting for a piece of jewellery AGUAdeORO, is a commitment to the planet and to improving the living conditions of the people working in the mines.
In addition, laboratory diamonds are also certified by independent gemmological laboratories such as GIA or IGI.
Are all culture stones perfect?
Like mined stones, a cultured stone contains inclusions and its colour is random. These characteristics make each stone unique.
A laboratory diamond cannot be created "a la carte" so that the characteristics of the stone can be programmed in advance. However, all stones produced in a laboratory will have the same strength, hardness and density properties as a stone mined
Minerals have been formed over millions of years through a mixture of specific elements, pressure and temperature. Today, science has been able to replicate these processes on a smaller scale, making it possible to create these minerals identically
Is a cultured stone of inferior quality?
No. Having the same physical, chemical and optical characteristics, the quality of a cultured stone will be subject to its intrinsic characteristics and external factors, such as the cutting and polishing of the stone. In other words, the same factors as a mined stone.
To better understand the difference between a mine stone and a laboratory stone, we can take as an example the domestic production of an ice cube. Ice forms naturally in places with low temperatures, such as on glaciers. Alternatively, you can artificially produce one in a freezer.
Both will be the same and with the same optical, physical and chemical qualities. The only difference will be the way they were made.
Is it possible to see the difference between a mine stone and a cultured stone with the naked eye?
No, only gemmology labs can tell the difference.
