Frequently Asked Questions

Everything you need to know about our lab-grown monocrystalline diamonds.

What is the difference between CVD and HPHT diamonds?

CVD (Chemical Vapor Deposition) diamonds are grown in a vacuum chamber using carbon-rich gas, resulting in high-purity, colorless crystals ideal for optics and electronics. HPHT (High Pressure High Temperature) diamonds mimic natural formation using extreme pressure and temperature, often producing yellow or brown diamonds suited for industrial abrasives and cutting tools.

Are your diamonds suitable for jewelry?

Yes. We offer lab-grown diamond jewelry with VVS-VS clarity and DEF color grading. Our CVD-grown diamonds are precision-cut (3EX) and available in loose stones from 1ct to 10mm for use in necklaces, earrings, and custom designs.

Can you customize diamond size and shape?

Absolutely. We provide OEM services for custom dimensions, orientations (e.g., 110 face), and polishing levels. Whether you need rectangular CVD plates or cylindrical optical sticks, we can tailor to your specifications.

What industries use your monocrystalline diamonds?

Our diamonds are used in semiconductor manufacturing, precision machining, medical devices (e.g., ophthalmic knives), quantum computing, high-power optics, audio stylus, and water treatment (via boron-doped electrodes).

How do you ensure quality?

We implement strict quality control at every stage—from raw material selection to final inspection. Each batch is tested for structural integrity, thermal conductivity, and optical clarity to meet international standards.
