IGI vs GIA Lab Grown Diamonds: Which Certificate is Right for You?


When considering a IGI vs GIA Lab Grown diamond, choosing a reputable certification lab is crucial. Two major players dominate the market: the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). Both are respected institutions, but they have some key differences when it comes to lab-grown diamonds.

IGI: Speed, Clarity, and Cost-Effectiveness

  • Faster and More Affordable: IGI certification is generally quicker and less expensive than GIA. This can make a significant difference, especially for larger retailers.
  • Detailed Grading: IGI consistently uses the international grading scales (D-Z for color and FL-I3 for clarity) for lab-grown diamonds, providing a clear picture of a diamond’s quality.
  • Market Leader: IGI has established itself as the leading lab-grown diamond certification lab due to its efficient and detailed approach.

GIA: Reputation and Resale Value (for Now)

  • Legacy of Trust: GIA has a long-standing reputation for rigorous grading in the natural diamond market. This can be a selling point for some consumers who prioritize tradition and resale potential.
  • Recent Shift: GIA has recently adapted its grading system to better accommodate lab-grown diamonds. However, many retailers still primarily offer GIA certification for natural diamonds.
  • Potential Resale Premium: While resale of lab-grown diamonds is a developing market, some believe a GIA certificate might hold a slight resale value advantage in the future.

Choosing the Right Certificate

Here’s a quick breakdown to help you decide:

  • Value and Transparency: If budget is a concern and you prioritize clear quality grading, IGI is an excellent choice.
  • Reputation and Resale (Potentially): If brand recognition and potential future resale value are paramount, GIA might be preferable.

The Bottom Line

Both IGI vs GIA Lab Grown offer reliable certification for lab grown diamonds. Ultimately, the best choice depends on your priorities and budget. Remember, purchasing from a reputable jeweler is key regardless of the certification body.
