Laboratory grown diamond rings

What are lab-grown diamonds?

Lab-grown diamonds, also known as synthetic, cultured, or created diamonds, are diamonds grown inside a laboratory using advanced technological processes that simulate the natural diamond creation process. Essentially, lab-grown diamonds have the same physical, chemical, and optical characteristics as mined diamonds. The difference lies in the origin of their formation. While mined diamonds require billion-year-old geological processes occurring deep within the earth's crust, lab-grown diamonds are carefully formed in just weeks or months under meticulously controlled lab environments.

When conditions of extreme heat and pressure are precisely replicated, carbon atoms arrange themselves into the iconic diamond crystal lattice structure. Advanced techniques like chemical vapor deposition (CVD) and high pressure, high temperature (HPHT) enable diamond seed crystals to grow layer-by-layer into glittering finished diamonds. The resultant gems exhibit exceptional clarity, colorlessness, and brilliance like top quality natural diamonds sourced from mines. As technology continuously improves, lab-grown diamonds are rapidly gaining recognition as legitimate diamond alternatives.

Are lab-grown diamonds real?

Yes, lab-grown diamonds are absolutely 100% real diamonds. They possess the same physical, chemical, and optical attributes as mined diamonds. When scrutinized by standard gemological instrumentation, trained gemologists cannot distinguish lab-grown diamonds from their mined counterparts. Like mined diamonds, lab-grown diamonds are composed of pure crystallized carbon and exhibit the same level of hardness, brilliance, fire, and scintillation. Both are genuine diamonds with identical visual appearances and durability. The singular difference lies in whether the diamond formed below earth’s surface or inside an advanced technological system.

So in essence, lab-grown diamonds are as real as mined diamonds. They sparkle with the same intensity, cut and polish the same way, get graded by the same standards, and stun with resplendent beauty equally. The misconception they are fakes or imitations stems from traditional notions that geological processes were the only means to create real diamonds. But state-of-the-art lab production validates that diamonds themselves are inherently real regardless of different origination pathways. When choosing lab-grown, buyers get glittering gems with identical grading certificates at more affordable prices.

How are lab-grown diamonds made?

Lab-grown diamonds are produced through advanced technological simulation of the natural diamond creation process occurring below earth's surface over billions of years. Two principal methods used are:

HPHT - High Pressure, High Temperature

First pioneered by GE in 1955, this process mimics the immense heat and pressure diamonds experience naturally deep within the earth’s mantle. A diamond seed crystal is exposed to temperatures exceeding 2500°C while under pressures over 1.5 million psi inside specialized supercomputers. This enables carbon atoms to concentrate and crystallize atop the seed.

CVD - Chemical Vapor Deposition

This breakthrough process developed in the 1980s occurs inside microwave plasma reactors. A hydrocarbon gas mixture activated by microwaves breaks down and releases carbon atoms that settle onto diamond seed plates in carbon-rich layers epitaxially. Continual deposition results in diamond crystals expanding into rough lab-grown diamonds.

Both HPHT and CVD rely on human-engineered technological expertise to duplicate natural conditions that create glittering diamonds underground through complex interplay between carbon, heat, and pressure over eons.

What's the difference between lab-grown diamonds and mined diamonds?

While essentially equivalent on a molecular level, lab-grown and mined diamonds have several key differences:

Origin: Mined diamonds result from compression of carbon deep inside the earth's mantle over billions of years. Lab-grown diamonds have identical compositions but originate from advanced technologies simulating natural diamond creation above ground.

Age: Mined diamonds are over 1-3 billion years old. Lab-created diamonds are grown in weeks to months.

Source: Mined diamonds are extracted from remote diamond mines across the globe requiring intensive resources. Lab diamonds are manufactured sustainably in monitored facilities.

Cost: Due to rarity, mined diamond prices are 50-75% higher across all color/clarity combinations. Lab diamonds deliver tremendous value at 30-40% savings.

Ethics: Mined diamond supply chains have historically lacked transparency and oversight with concerns like conflict sourcing, unsafe working conditions, and environmental damage. Lab diamond producers emphasize social responsibility with 100% traceability.

In essence, lab vs. mined diamonds offer consumers an ethical choice without compromising beauty, quality, or longevity. Savings from lab origins pass directly onto buyers as well.

Are lab-grown diamonds ethical and Eco-friendly?

Yes, lab-grown diamonds rate exceptionally highly for environmental sustainability and ethical production compared to mined diamonds. Mined diamond extraction requires immense energy expenditures and heavy machinery operation leading to soil erosion, deforestation, sinkholes, waterway harm, and displaced ecosystems. Dangerous and exploitative working conditions for miners also persist in some areas.

Conversely, lab diamond manufacturing has minimal environmental impact since cutting-edge production takes place securely inside high-tech indoor facilities. State-of-the-art technology powered by renewable energy sources emits virtually zero waste while efficiently growing gems layer-by-layer. Lab diamond producers proudly emphasize eco-conscious and socially responsible business practices promoting transparency, non-discrimination, livable wages, and safe working conditions along 100% traceable supply chains.

When customers select lab grown diamond rings like engagement rings, they can feel assured they are making an ethical choice aligned with modern values, not supporting outdated mining practices that exploit people and habitats for diamond extraction from endangered ecological regions. Ultimately, lab diamonds are the future offering consumers conflict-free, eco-friendly, economical, stunning heirlooms.

What are the pros and cons of lab-grown diamond engagement rings?


  • Significant cost savings of 30-40% off comparable mined diamonds enables choosing larger, higher quality center stones
  • Graded by same standards as mined so guaranteed exceptional cut, color and clarity
  • Eco-friendly and conflict-free for guiltless purchasing and wearing
  • Identical optical properties mean dazzling brilliance and fire
