Products Description
Lab Grown Diamond are diamonds manufactured in a laboratory, as opposed to diamonds mined from the Earth. The gemological and industrial uses of diamond have created a large demand for rough stones. This demand has been satisfied in large part by synthetic diamonds, which have been manufactured by various processes for more than half a century. However, in recent years it has become possible to produce gem-quality synthetic diamonds of significant size.
HPHT diamonds are a popular choice for use in fine jewelry, where they can be paired with various metals such as gold, platinum,and silver. These diamonds are readily available at wholesale prices and are certified for purity and clarity, making them are liable choice for jewelry manufacturers who incorporate them into their designs.
Affordable pricing is a significant advantage of HPHT diamonds over natural stones.which can be quite expensive due to the lengthy mining process, supply chain, and middle man commissions involved. As HPHT diamonds come directly from the laboratory they are an excellent choice for those seeking affordable diamond options.

After receiving the ashes, we store them individually in numbered packages to ensure your sample is not confused with others. The
package will only be opened once it reaches the laboratory.

Upon receiving the sample, the laboratory will grind the ashes into powder using a milling device and conduct a chemical analysis
to ensure we can extract enough carbon. The chemical composition analysis also serves as a unique identifier for the ashes.

The ash powder is placed in a vacuum furnace and subjected to high temperatures for three hours, extracting carbon while a minimal
amount of trace elements remains.

Extracted carbon and metal media are placed in a synthetic block

The synthetic blockis placed in a diamond cultivation machine. This heavy machine simulates the extreme high-temperature and
high-pressure environment experienced by natural diamonds in the Earth's mantle. Over several days, the chemical bonds of the
carbon atoms in the graphite break and recombine on a diamond seed to form a diamond structure.

After the white capsule containing the raw diamond is removed and broken open, the disc inside is placed in a specific liquid to
dissolve its surface, revealing a raw diamond. After being cut and polished by experts, a new diamond is created.
