Understanding Lab Grown Diamonds


In exploring the realm of lab grown diamonds, I focus on what they are, the technology behind their creation, and how they stack up against natural diamonds.

What Are Lab Grown Diamonds?

Lab grown diamonds are true diamonds created in controlled environments using advanced technological processes. Despite their synthetic origins, these diamonds possess the same physical, chemical, and optical properties as their natural counterparts found in the earth.

The Science Behind Creation: HPHT and CVD

High-Pressure, High-Temperature (HPHT) and Chemical Vapor Deposition (CVD) are the cornerstone technologies in synthetic diamond creation.

HPHT mimics the natural formation conditions with high pressure and temperature to transform carbon into a diamond. Alternatively, CVD grows diamond crystals layer by layer from a gas mixture, typically involving a hydrocarbon gas like methane.

  • HPHT Process:
    • High pressure and temperature
    • Transformation of carbon structure
  • CVD Process:
    • Layer-by-layer crystal growth
    • Gas mixture, often containing methane

Comparison Between Lab-Created and Natural Diamonds

Composition Chemically identical to natural diamonds, composed of pure carbon crystallized in an isometric crystal system. Also composed of pure carbon crystallized in an isometric crystal system.
Formation Time Can be produced in a matter of weeks to months. Formed over millions to billions of years.
Cost Generally more affordable than natural diamonds. Pricing influenced by factors such as rarity, size, and quality.
Environmental Impact May be considered a more environmentally friendly option due to reduced environmental impact compared to mining. Mining diamonds has environmental considerations, including habitat destruction and carbon emissions.
Market Perception Perceived by some as a sustainable and ethical choice. Valued for their rarity and natural origin.

The differences between lab-created and natural diamonds are primarily in their origin and price point.

Lab grown diamonds are typically less expensive—about 30-40% the price of a natural diamond. While they share the same crystal structure and appearance, the resale value of lab-grown diamonds is usually lower.

  • Price:
    • Lab grown: Approximately $1,200 per carat
    • Natural: Approximately $4,200 per carat
  • Resale Value: Lower for lab grown diamonds

Both HPHT and CVD diamonds cater to consumers seeking ethically sourced options without compromising on the diamond’s brilliancy or composition.
