Are Lab Grown Diamonds Real Diamonds?

At Impress Jewelry Creations, we understand that the essence of a diamond isn't just in its sparkle, but also in its story. When considering lab-grown diamonds, many clients wonder about their authenticity. Are they "real" diamonds? This question deserves a detailed exploration, especially for those contemplating these gems for their fine jewelry.

The Science Behind Lab-Grown Diamonds

Lab-grown diamonds are indeed real diamonds, but with a twist in their origin. They are created in controlled environments using advanced technological processes that replicate the natural conditions under which diamonds form in the Earth.

Formation Process

High Pressure High Temperature (HPHT)

  • Method: Mimics the natural conditions deep within the Earth, applying high temperatures and pressures to a small diamond seed.
  • Materials: A carbon source, typically graphite, melts around the seed, gradually forming a diamond.

Chemical Vapor Deposition (CVD)

  • Method: Involves gas in a chamber heated to high temperatures.
  • Process: Gasses rich in carbon, like methane, are broken down; the carbon atoms then deposit on a substrate, slowly crystallizing into diamond.

Identical Characteristics

  • Composition: Both mined and lab-grown diamonds are made of crystalline carbon.
  • Properties: They share the same physical and optical properties, including hardness, refractive index, and the unique ability to disperse light.

Authenticity and Recognition of Lab-Grown Diamonds

Lab-grown diamonds have firmly established their legitimacy in the world of gemology. Recognized globally by prestigious gemological institutes, these diamonds are celebrated for their authenticity and adherence to the same evaluation standards applied to mined diamonds. Let’s delve into how these gems are recognized and certified, bolstering their status in the jewelry market.

Global Recognition

  • Gemological Institute of America (GIA): As a leading authority in gemology, the GIA recognizes lab-grown diamonds and provides detailed reports that affirm their identity as genuine diamonds. These reports are crucial for both consumers and the industry, as they validate the diamond’s nature and origin.
  • International Gemological Standards: Other notable organizations, like the International Gemological Institute (IGI) and the American Gem Society (AGS), also recognize and certify lab-grown diamonds, further solidifying their status worldwide as real diamonds.

Certification and Grading

Lab-grown diamonds undergo rigorous assessment processes similar to those used for mined diamonds, focusing on the universally accepted 4Cs of diamond quality: Color, Cut, Clarity, and Carat.

Standardized Grading

  • Color: Lab-grown diamonds are evaluated for how colorless they are, unless they are fancy colored diamonds, in which case they are assessed based on the intensity of their color.
  • Cut: The cut grade determines how well a diamond’s facets interact with light, playing a critical role in its brilliance. Lab-grown diamonds can be cut into any shape and style, providing flexibility in design while maintaining high optical performance.
  • Clarity: This measures the cleanliness or purity of a diamond and is assessed by identifying the number, size, relief, nature, and position of inclusions and blemishes.
  • Carat: Carat weight is measured with the same precise electronic scales used in grading mined diamonds, ensuring accuracy.


  1. Comprehensive Analysis: Certificates for lab-grown diamonds provide a detailed analysis of their physical and optical properties. This includes not only the 4Cs but also advanced light performance metrics and structural features.
  2. Traceability and Transparency: Each certificate also details the diamond's origins, clearly distinguishing it as lab-grown. This transparency is crucial for consumer trust and allows buyers to make informed decisions based on their preferences.

Enhancing Buyer Confidence

The detailed grading and certification of lab-grown diamonds are critical in enhancing buyer confidence. By offering a clear, standardized assessment of these diamonds, gemological institutes help demystify their value and ensure that consumers are well-informed about their purchases.

  • Educational Role: Certificates often serve an educational role, helping consumers understand what makes each diamond unique and valuable.
  • Verification: For those investing in lab-grown diamonds, having a reliable certificate means that the gem's attributes have been verified by experts, reducing the risk of misrepresentation and fraud.

Advantages of Lab-Grown Diamonds in Fine Jewelry

Lab-grown diamonds offer several unique benefits, particularly appealing to those seeking both luxury and modernity in their jewelry.

Design Flexibility

  1. Variety: Available in a range of sizes and cuts, often more consistently than mined diamonds due to controlled production.
  2. Customization: Allows for more personalized jewelry designs without the constraints of rarity and high price tags associated with certain cuts and carats in mined diamonds.

Quality Assurance

  1. High Purity: Often possess fewer impurities than natural diamonds because the controlled environment minimizes the common natural inclusions.
  2. Brilliance and Fire: They exhibit exceptional sparkle and fire, crafted to meet specific optical standards.

Consumer Perception and Market Trends

As the popularity of lab-grown diamonds increases, so does their acceptance in the luxury jewelry market. They are now celebrated not only for their environmental and ethical considerations but for their quality and technological marvel.

Shift in Consumer Demand

  • Growing Popularity: Increasingly chosen by consumers who value both technology and tradition in their jewelry choices.
  • Market Acceptance: Recognized by jewelry connoisseurs and experts as viable and valuable options for engagement rings, wedding bands, and other fine jewelry.
