Diamonds have long been symbols of brilliance and beauty. But today, a cutting-edge alternative is reshaping the industry: CVD diamonds. They sparkle, shine, and yes — they’re absolutely real. Unlike American Diamond (Quartz Crystal) and CZ (Cubic-Zirconia) they are not mere simulants.

What Is a CVD Diamond?

CVD stands for Chemical Vapor Deposition, a high-tech method used to grow diamonds in a lab. Unlike mined diamonds formed over billions of years deep within the Earth, CVD diamonds are grown in clean lab settings using carbon-rich gases. The result? A diamond that’s optically, chemically, and physically identical to a natural one.

Supreme Green Diamond produces premium CVD diamonds using solar energy, making them not just gorgeous — but ‘Green’ in its true sense.

Why Are CVD Diamonds Popular?

More and more people are choosing lab-grown diamonds — and here’s why:

• Authentic Sparkle: Indistinguishable from mined diamonds, even to trained gemmologists.

• Eco-Friendly: No destructive mining or conflict sourcing.

• Affordable Luxury: 50–90% cheaper than traditional diamonds.

• Versatile Applications: From high-end jewellery to cutting-edge technology.

How Are CVD Diamonds Made?

Think of growing a diamond like nurturing a crystal garden. Here’s a simplified look:

1. Seed Crystal: A tiny diamond fragment is placed in a chamber.

2. Carbon Gases Added: Methane and hydrogen gases fill the space.

3. Microwave Energy: Breaks gases into individual carbon atoms.

4. Layer-by-Layer Growth: Carbon atoms deposit on the seed and form a diamond.

5. Cut & Polish: The diamond is refined into sparkling perfection.

The Many Grades of CVD Diamonds

At Supreme Green Diamond, lab-grown diamonds aren’t just for jewelry — they’re engineered for high-performance industries too:

Supreme Green Diamond offers specialized CVD diamond grades for diverse applications. Our Quantum Grade features intentionally doped diamonds designed for quantum sensors and advanced research in futuristic computing. The Electronic Grade enhances high-power electronics and aerospace technology with superior durability and efficiency. For thermal management, our Thermal Grade provides exceptional heat dissipation (5x better than copper), making it ideal for lasers, smartphones, and spacecraft components. Optical Grade diamonds deliver crystal-clear clarity with high transmission percentages, perfect for medical lasers and precision instruments. The Mechanical Grade offers unmatched hardness for heavy-duty industrial tools and coatings. For consumers, our Jewelry Grade provides eco-friendly diamonds with identical sparkle to mined stones at 30% less cost, suitable for rings, necklaces, and earrings.

A Quick History of CVD Diamonds

• 1950s–1980s: First attempts to grow diamonds in labs — challenging and costly.

• 1990s–2000s: Improved tech makes stronger, clearer lab diamonds.

• 2010s–Now: CVD diamonds rival natural ones and serve industries from fashion to space.

Extra Benefits of CVD Diamonds

• Purity: Fewer imperfections than some mined diamonds.

• Customization: Available in stunning colors like pink and blue.

• Durability: Just as hard and long-lasting.

• Sustainable Production: Especially with solar-powered labs like ours.

FAQs About CVD Diamonds

Are CVD diamonds real?

Yes — they’re genuine diamonds, just grown in a lab rather than underground.

Can CVD diamonds be used in jewellery?

Absolutely. They’re perfect for rings, necklaces, earrings — and they look identical to mined stones.

Why are CVD diamonds better for the environment?

They avoid mining damage, and at Supreme Green Diamond, they’re grown using renewable solar power.

Do CVD diamonds have other uses?

Yes! They’re also used in electronics, EVs, heat spreaders, and even quantum tech.

Can they be colored?

Definitely. Lab-grown methods allow vibrant shades beyond classic white.
