HPHT vs. CVD
Lab-Grown Diamonds
Ethical. Sustainable. Brilliant.
Lab-grown diamonds are the modern, conscious alternative to mined stones. Created through advanced scientific methods, they possess the same chemical, physical, and optical properties as natural diamonds — without the environmental damage or ethical concerns of traditional mining.
Using either HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) technologies, we replicate nature’s diamond-forming conditions in state-of-the-art laboratory environments. The result: exceptional diamonds that offer remarkable brilliance and durability, ready to be cut into any shape or size.
HPHT Process
Forged by Heat. Perfected by Pressure.
The HPHT method mimics the intense conditions found deep within the Earth. Carbon is subjected to extreme pressure and temperature, transforming it into crystalline diamond in a matter of weeks.
How it works:
A small diamond seed (often a lab-grown stone) is placed inside a specialized containment cube.
The cube is compressed to replicate the immense pressures found underground.
Electric pulses generate temperatures exceeding 1,500°C.
The combination of heat and pressure causes the carbon to crystallize around the seed.
After several weeks, a rough lab-grown diamond emerges.
The stone is cut and polished using laser precision and traditional techniques.
The final diamond undergoes certification by leading gemological laboratories such as GIA or IGI, verifying it as HPHT-grown and assessing its cut, color, clarity, and carat.
CVD Process
Grown with Light. Refined with Science.
The CVD process uses plasma technology to build diamonds atom by atom in a controlled, contaminant-free chamber. It results in diamonds with exceptional purity and structure.
How it works:
A thin diamond seed (~300 microns thick, 10x10mm) is carefully selected and meticulously cleaned.
The seed is placed inside a vacuum-sealed chamber, isolated from impurities.
The chamber is flooded with a carbon-rich gas, then heated to extreme temperatures.
As the gas ionizes into plasma, carbon atoms break down and begin bonding to the seed.
Over the course of 2–3 weeks, layer by layer, the diamond grows — increasing in carat weight.
The result is a rough square-shaped diamond, ready for cutting and finishing.
The diamond is refined with precision cutting and polishing to achieve its final form.
Grading labs such as GIA assess the final product, certifying it as CVD-grown and evaluating all 4Cs: cut, color, clarity, and carat.
Certified Perfection
Every lab-grown diamond we produce is independently graded and certified by internationally recognized institutions including GIA, IGI, EGL USA, and HRD — ensuring full transparency and confidence in your investment.
Whether grown through HPHT or CVD, our diamonds embody purity, performance, and purpose — ideal for the modern collector or designer who values beauty without compromise.
