Crystal Growth
Diamond seeds are loaded into CVD reactors or HPHT presses and grown over 10-30 days depending on method and target size.
Planning and Sawing
Raw crystals are analyzed using 3D imaging software to determine optimal cutting orientation and maximize carat weight.
Bruting and Polishing
Master cutters shape and polish each diamond using computer-assisted bruting followed by hand polishing on scaife wheels.
Grading and Certification
Finished diamonds undergo independent grading by IGI or our in-house GIA-graduate gemologists for cut, color, clarity and carat.

Everything you need to know about partnering with us for lab-grown diamond wholesale and manufacturing.
Our standard MOQ for lab-grown diamond wholesale accounts is 50 carats per category. For melee parcels, we offer starter lots starting at 100 pieces per size. Enterprise clients with annual commitments exceeding 5,000 carats qualify for custom MOQ structures and dedicated inventory allocation.
Both CVD and HPHT diamonds are real diamonds with identical chemical composition, hardness, and optical properties. CVD tends to perform better in larger sizes and fancy colors, while HPHT is ideal for standard white melee. Both receive IGI certification and are equally suitable for fine jewelry.
Yes. Our lab diamond melee program is designed for jewelry manufacturers requiring consistent, calibrated stones. We supply round melee from 0.8mm to 2.7mm in single-size parcels of 1,000-10,000 pieces, laser-sorted to ensure size consistency within 0.05mm tolerance.
Our fancy color lab diamond program covers vivid yellow, intense blue, soft pink, green, orange, and champagne shades. Yellow and blue are most popular, with consistent supply in 0.10 to 3.00 carat sizes. Custom color matching is available for brand-specific proprietary hues.
