Product Description

Lab Grown Rough Diamonds – High-Quality Synthetic Diamond Rough for Wholesale

Discover our premium collection of lab-created rough diamonds – the smart, ethical, and cost-effective choice for jewelers, diamond cutters, and manufacturers worldwide.

What Are Lab Grown Rough Diamonds?

Also known as synthetic, man-made, or cultivated diamonds, our lab-grown rough diamonds are produced in controlled laboratory environments using cutting-edge technology. They possess the exact same crystal structure, hardness (10 on the Mohs scale), refractive index, and brilliance as natural earth-mined diamonds – the only difference is their origin.

Two Advanced Growth Technologies

HPHT (High Pressure High Temperature) Diamonds

Replicating the extreme conditions deep within the Earth's mantle, our HPHT rough diamonds are grown at pressures of 5–6 GPa and temperatures of 1400–1500°C. This method excels at producing larger carat rough crystals with excellent D–F color grades and is widely preferred for high-purity gem-quality diamonds.

CVD (Chemical Vapor Deposition) Diamonds

Our CVD diamond rough is grown by depositing carbon atoms layer by layer onto a diamond seed substrate inside a vacuum chamber. This technology offers superior control over clarity and is renowned for producing Type IIa diamonds with exceptional transparency and minimal inclusions.

Specifications & Grading

Carat Range: 0.5ct – 10+ct rough stones (custom sizes available upon request)
Color Grades: D, E, F, G, H (colorless to near-colorless)
Clarity Grades: VVS1, VVS2, VS1, VS2, SI1
