The New Era of a diamond
JOY COLORi leads the industry by exclusively introducing CVD (Chemical Vapor Deposition) lab-grown diamonds from the United States, registered under the trademark "JOY COLORi Future Diamonds." These diamonds are certified with Carbon Neutral® and Climate Neutral certifications, as well as the Sustainable Butterfly logo. Lab-grown diamonds are a perfect fusion of art, science, and human ingenuity. By simulating the natural underground environment in a laboratory, they give birth to one of Earth's most romantic creations.
The New Era of a diamond
Our diamonds are lab-grown using the Chemical Vapor Deposition (CVD) method, and are known as one of the most romantic inventions of modern society.
What is Lab Grown Diamond (LGD)?
Lab-grown diamonds are created in a laboratory by replicating the high temperature and pressure conditions found deep within the Earth. Since the growth process mirrors the natural formation of mined diamonds, lab-grown diamonds, like their mined counterparts, may contain inclusions that reflect the authenticity of their formation.
In terms of chemical, optical, and physical properties, lab-grown diamonds are nearly identical to mined diamonds. They retain the same uniqueness and beauty, offering a new jewelry option that combines both elegance and sustainability.
How CVD Lab-Grown Diamonds Are Made?
CVD (Chemical Vapor Deposition) is an advanced technology used to grow diamonds in a laboratory. Compared to the traditional HPHT (High Pressure High Temperature) method, the sophisticated CVD process requires precise technical control over an extended period during the production of lab-grown diamonds, ensuring the creation of diamonds with exceptional quality.
Under the guidance of scientists and engineers, the CVD diamond process begins with a high-quality Type IIA diamond seed (the lattice structure of lab-grown diamonds) placed in a vacuum chamber. Carbon atoms are then formed under high temperature and immense pressure, bonding together to form a crystal lattice structure. Once fully formed, the diamond undergoes cutting and polishing to reveal its maximum brilliance. After passing through rigorous tests, including millions of simulations, the process ensures that the hardness, physical, chemical, optical, and thermal properties of lab-grown diamonds are identical to those of mined diamonds, reflecting the same natural growth process.
The growth of diamonds requires precise control over temperature, pressure, gas composition, and the growth period. After the diamond is grown, the rough diamond undergoes stringent quality inspections before being cut and polished by expert craftsmen. Finally, the diamond is sent to international gemological institutions for certification.
CVD Diamond Growth Process
The uniqueness of CVD Lab-Grown Diamonds: The "As Grown" Concept
The CVD (Chemical Vapor Deposition) lab-grown diamonds introduced by JOY COLORi are “As Grown,” meaning they undergo no additional treatments or color enhancements after growth, just like the natural formation process of mined diamonds. Some industry players may attempt secondary treatments, but international diamond certification will provide proof of such treatments.
Each CVD lab-grown diamond from JOY COLORi is meticulously cut with precision, following perfect proportions, and is designed to exhibit a brilliant array of colors under light. They meet the international 4C standards for cut, color, clarity, and carat weight. Every “JOY COLORi Future Diamond” has its own unique DNA, ensuring the authenticity and individuality of each piece.
JOY COLORi Future Diamond" International Diamond Certification
Each CVD lab-grown diamond from JOY COLORi is engraved with a patented marking and a unique grading laboratory certificate number on the girdle. This not only guarantees the quality of the diamond but also certifies its origin and authenticity. These engravings ensure that every diamond has its own unique identity, making it traceable and verifiable.
Every “JOY COLORi Future Diamond” holds Carbon Neutral® certification, Climate Neutral sustainability certification, and the Butterfly Sustainability Mark certification. Additionally, they are certified by international diamond grading institutions, including the Gemological Institute of America (GIA), International Gemological Institute (IGI), and Gem Certification & Assurance Lab (GCAL). These institutions are renowned for their strict grading standards and impartiality, ensuring transparency and reliability regarding the origin and quality of each diamond.
FAQ about lab-grown diamonds
To acquire real diamonds, mining is no longer needed. This way reduces pollution and inhumane exploitation of miners to avoid producing “blood diamonds.” Lab-grown diamonds are a beautiful choice more friendly to Earth and the future.
Yes, lab-grown diamonds are real diamonds.
The head of GIA says, “Lab-grown diamonds are real diamonds, with the same physical and chemical composition as mined diamonds.”
The FTC says, “Lab-grown diamonds are real diamonds.”
In July of 2018, the Federal Trade Commission (FTC) published a jewelry commercial guideline and emphasized that lab-grown diamonds share identical chemical, physical, and optical properties with mined diamonds. The FTC revised the definition of a diamond and stated that “a diamond is a kind of mineral made of pure carbon crystallized in the isometric system.” Nowadays, the word “natural” doesn’t apply to mined diamonds anymore while “artificial” no longer applies to lab-grown diamonds.
Not all lab-grown diamonds are the same. Many lab-grown diamonds are produced in factories that rely on fossil fuels, meaning their carbon footprints are as large as traditional mines. The lab-grown diamonds JOY COLORi imports are the lead in the industry, with ®carbon neutral, climate neutral, and the ESG+ Certified Brand Butterfly Mark.
Every diamond should be graded under the 4C international standards so the consumers can be assured of their purchase. And every JOY COLORi diamond has been certificated by international diamond grading institutes.
