We believe that the splendor of jewelry can go hand in hand with ethics and environmental sustainability.
Choosing high-quality, sustainable lab-grown diamonds is our way of showing care for the planet and making a commitment to the future.
"Strive with Us for a Radiant and Sustainable Future"
Lab-grown diamonds have a smaller ecological footprint, aligning with sustainable development principles.
Avoids conflict diamonds, ensuring the ethical and legal origin of diamonds.
Guarantees high-quality diamonds through strict selection by professional teams and international certification bodies.
Lab-grown diamonds, also known as synthetic or cultivated diamonds, are diamonds created in a controlled laboratory environment. These diamonds are chemically, crystallographically, optically, and physically identical to natural diamonds, with the only difference being their growth environment.The manufacturing process of laboratory diamonds is more controllable, predictable, and does not harm the natural environment.
LusLumin's team consists of experienced FGA (Fellowship of the Gemological Association of Great Britain) gemmologists who are responsible for selecting the finest diamonds. The selected lab-grown diamonds are then subjected to testing and certification by professional appraisal institutes such as IGI (International Gemological Institute) or GIA (Gemological Institute of America). The appraisal reports provide detailed descriptions of the diamond's characteristics, including whether it is a natural diamond or a lab-grown diamond.
Offers detailed diamond grading reports and certifications and is the largest independent gemmological laboratory globally.
An authoritative institution for gemmological research worldwide, it established the 4C standard for diamonds and provides authoritative diamond grading certificates.
Experienced graduate gemologists conduct further evaluations under controlled conditions, detailing the relevant gemstone characteristics according to the strictest international system. Four main factors are considered when judging the quality and value of diamonds. They are the 4Cs of diamonds: carat weight, color, clarity, and cut.
Diamonds of high quality typically exhibit a colorless to near-colorless appearance, which is more valuable. LusLumin opt for lab-grown diamonds graded H and above, ensuring a vibrant and clear color that rivals that of natural diamonds.
High-quality diamonds are characterized by minimal visible inclusions or blemishes. Our selection at LusLumin includes only lab-grown diamonds with VS clarity or better, guaranteeing near-flawless transparency and purity.
An exceptional cut can enhance a diamond's sparkle and fire, augmenting its desirability and worth. The diamonds we feature are meticulously cut to ensure optimal proportions and symmetry, maximizing their visual impact.
High-quality lab-grown diamonds are typically of an appropriate carat weight that aligns with other quality metrics. LusLumin offer a diverse range of carat weights for our lab-grown diamonds to cater to various customer preferences and budgets.
LusLumin has made a conscious choice to predominantly select diamonds that are synthesized using the Chemical Vapor Deposition (CVD) method for its collection. This method is renowned for producing diamonds with exceptional purity and quality, aligning with LusLumin's commitment to offering only the best in lab-grown diamonds.
The CVD process involves the deposition of carbon atoms from a gaseous mixture onto a diamond seed in a vacuum chamber. This technique allows for the controlled growth of diamonds with a high degree of uniformity and fewer inclusions, resulting in gems that are not only visually impressive but also environmentally sustainable.
High Pressure High Temperature (HPHT) Method
- Principle: Simulates the high-pressure, high-temperature conditions of the Earth's mantle to transform carbon into diamonds.
- Process: Carbon source is placed in a high-pressure chamber and subjected to extreme temperatures and pressures, causing carbon atoms to rearrange into diamond crystals.
- Advantages: Diamonds can be produced quickly, suitable for manufacturing smaller gem-quality diamonds and industrial diamonds.
- Applications: This method is commonly used for producing industrial diamonds and smaller gem-quality diamonds.
Chemical Vapor Deposition (CVD) Method
- Principle: In a low-pressure environment, carbon atoms are deposited layer by layer by decomposing gas, forming diamond crystals.
- Process: Carbon source gas (such as methane) is decomposed in a low-pressure plasma, and carbon atoms are deposited on a diamond substrate, growing layer by layer to form a diamond.
- Advantages: Can produce large-area, high-purity diamonds, suitable for manufacturing gem-quality diamonds.
- Applications: The CVD method is widely used for producing high-quality gem diamonds and thin-film diamonds.
Lab-grown diamonds are meticulously cultivated by expert scientists in precisely controlled laboratory settings, matching natural diamonds in chemical composition and exceptional optical performance. The fundamental distinction lies in their origin——nature versus scientific cultivation – and the resulting rarity difference. Luslumin's lab-grown diamonds are pure carbon creations, indistinguishable from mined diamonds in terms of optical, physical, and chemical attributes. It's akin to comparing ice made in a freezer with ice harvested from a glacier; both exhibit the same chemical, physical, and optical properties regardless of origin. Our diamonds undergo a simulated natural crystallization process within the nurturing environment of modern technology.
Lab-grown diamonds hold high value, often priced lower than comparable quality natural diamonds. Their worth is still determined by the classic 4C criteria (cut, color, clarity, and carat weight), and they are increasingly appreciated by consumers who champion sustainable fashion.

Lab-grown diamonds cost about 40% less than mined diamonds listed on Rapnet, primarily because mined diamonds can change hands up to 20 times, crossing multiple countries, before reaching consumers, with each step adding to the cost. In contrast, Luslumin's lab-grown diamonds go straight from our lab to our manufacturing facility to you, streamlining the supply chain and reducing costs.
LusLumin is committed to pursuing exceptional quality standards. We meticulously select high-quality cultured diamonds that are above H color grade and VS clarity to complete our creations. Each diamond undergoes rigorous screening to ensure it meets our stringent quality requirements. For diamonds over 0.5 carats, we can provide authoritative certificates from the GIA (Gemological Institute of America) or IGI (International Gemological Institute) to attest to their quality and authenticity. These certificates include a unique identification number corresponding to the diamond's girdle, which can be verified using a 10x magnifying glass.If you require a certificate for your diamond, you have the option to request additional shipping at the time of purchase. We promise that every LusLumin cultured diamond will bring you an extraordinary jewelry experience with its exceptional quality and professional certification.
We are committed to making lab-grown diamonds a more accessible and desirable choice for everyday fine jewelry, using only the finest materials.
Our team of experts brings a wealth of knowledge and experience, ensuring that you receive the highest quality diamonds, exceptional craftsmanship, and the most competitive prices without the hassle of comparison shopping.
