Progress Lab Grown Diamond Factory
Advanced Semiconductor's in - house laboratory carefully cultivates diamonds. Relying on decades of accumulated precision manufacturing technology and material R & D experience in the semiconductor industry, it has built a domestically leading R & D system for the entire process of cultivated diamonds. The laboratory has broken through the bottlenecks of traditional cultivation technologies and applied core capabilities such as high - precision environmental control and plasma physics regulation in the semiconductor field across industries, injecting the rigorous standards of "chip - level" into diamond cultivation.
In the core cultivation process, the laboratory uses self - developed microwave plasma chemical vapor deposition (MPCVD) equipment. Using 99.999% high - purity methane as the carbon source, it creates a stable growth environment on a special molybdenum substrate. Through the AI intelligent system, the growth temperature of around 1000℃, the vacuum degree of 0.1mbar level, and the plasma density are regulated in real - time to ensure that the diamond crystals grow orderly along the (111) crystal plane. The growth rate per hour is precisely controlled at 0.08 - 0.12mm, which not only ensures the integrity of the crystal but also avoids the embedding of impurities.
Crafted in China, Leading the Global CulturedDiamond Industry
China is not merely a manufacturing hub but the core driving force in the global lab-grown diamond sector. Accounting for the vast majority of worldwide production, China has mastered both CVD and HPHT core technologies with unprecedented scale and precision.
At Advanced Technology, our cultured diamonds are built not just on volume, but on a commitment to consistent quality, advanced engineering, and sustainable innovation. By controlling the complete supply chain—from raw materials to cutting-edge growth reactors—we deliver diamonds of exceptional purity and outstanding value, each fully compliant with the highest international certification standards such as IGI.
When you source cultured diamonds from our company, you are partnering with the most reliable and efficient origin in the industry. Choose certainty. Choose leadership.
lEADING GLOBAL
From Lab to Your Doorstep
We ensure every cultured diamond delivered to you boasts exceptional quality and full certification through a highly controlled and transparent process.
Growth
In our state-of-the-art labs, we employ HPHT (High-Pressure High-Temperature) or CVD (Chemical Vapor Deposition) technology to replicate natural diamond formation. By precisely controlling temperature, pressure, and gas composition, carbon atoms crystallize layer by layer, growing into pure diamond crystals. This is the foundation of quality.
Cutting & Polishing
Experienced artisans meticulously design and cut each diamond rough. Using high-precision equipment, we ensure every facet achieves optimal proportions, symmetry, and polish to maximize the diamond’s fire, brilliance, and scintillation. Superior cut is what brings a diamond to life.
Grading & Certification
After cutting, each diamond is rigorously evaluated by independent authorities like IGI (International Gemological Institute) . They professionally grade the diamond’s Color, Clarity, Cut, and Carat Weight (the 4Cs) and issue an official certification report. This “identity card” is your ultimate guarantee of quality and value.
Global Shipping
Following strict final quality checks and secure packaging, your order is shipped via our trusted international logistics partners. We provide full tracking and insured shipping to ensure safe and timely delivery to your door anywhere in the world, completing the final link from our warehouse to you.
What are lab-grown diamonds?
Lab-grown diamonds are real diamonds. Our company supports mass production, custom shapes, and diamond wholesale.

Explore lab-grown diamonds
Progressive Semiconductor. Relying on CVD (cultivation technology) and the company's self - built high - standard laboratory, the Progressive team has achieved precise cultivation of high - purity artificial diamonds. These diamonds have obtained IGI certification, with each diamond having its own certificate, and they support cutting into various shapes. Using advanced technology and equipment, it restores the natural diamond formation environment in the laboratory. By using small diamond seeds to induce the natural crystallization of diamonds, diamonds with exactly the same physical, chemical, and optical properties as natural diamonds are cultivated on the surface of the earth. Therefore, cultivated diamonds are genuine diamonds.

Differences between synthetic diamonds and natural diamonds
From the chemical essence, core physical properties to daily visual experience, there is no essential difference between artificial diamonds and natural diamonds: both are sp³ hybrid crystals composed of pure carbon elements, with a Mohs hardness of level 10 (the highest hardness in nature). The key physical parameters such as thermal conductivity, refractive index, and dispersion value are exactly the same. Even when observed with a 10 - fold magnifying glass, there is no difference in the fire and luster performance of the two. Ordinary consumers and even some non - professional appraisers cannot distinguish them with the naked eye. In practical applications, whether worn as jewelry (both have the same dazzling texture and decorative value) or used in industrial fields (such as chip heat dissipation and precision cutting, both rely on ultra - high hardness and thermal conductivity), the functions of the two are completely equivalent. Moreover, international authoritative appraisal institutions such as IGI have the same 4C rating standards (weight, color, clarity, and cut) for both, and only indicate the source attribute of “cultivated” or “natural” in the test report, rather than quality differences. In short, except for the different formation environments (natural diamonds are formed through hundreds of millions of years of geological processes, while artificial diamonds are cultivated controllably in the laboratory) and sources, there is no difference between the two in terms of quality, performance, and use value.

Advantages of artificially cultivated diamond products
High clarity and high purity: Through the dual control of "in-situ optical monitoring + laser Raman spectroscopy detection", the clarity of the finished products generally reaches above VVS1 level (only containing extremely tiny inclusions invisible to the naked eye), the content of sp³ hybridized carbon reaches over 99.99%, and there are no heterocyclic carbon and graphite-phase impurities inside the crystals; Low stress and high stability: The internal stress value of the crystals is lower than 50MPa (the industry average is about 80 - 100MPa), which avoids cracks caused by stress concentration during the wearing or processing of diamonds, and the physical properties are more stable during long-term wearing or industrial use; Controllable and uniform color: It can not only stably produce colorless diamonds of grade D - F (only 0.01% of natural diamonds are grade D), but also customize colored diamonds such as pink and blue by precisely regulating trace elements. Moreover, the color distribution is uniform, without the common "uneven color band" problem of natural colored diamonds.
