1. Why Certification Matters in Lab-Grown Diamonds

 

Certification is the only way to ensure that your lab diamond is genuine, high-quality, and accurately graded. At Solitique, we believe in absolute transparency.

2. What exactly is a Diamond Certificate?

 

A lab grown diamond certificate is more like a diamond's official identity, outlining its quality and characteristics. The diamond certificates assess the diamonds based on the 4Cs– carat weight, color, clarity, and cut quality. 

It also provides in-depth information on proportions, clarity specifics, and any treatments or enhancements. To ensure authenticity, always purchase a diamond with a certificate from a highly reputable grading entity like IGI, GIA or SGL.

3. What Does Certification Mean for You?

a. Quality Assurance:

Each and every diamond that goes through the certification process is rigorously tested for cut, color, clarity, and carat weight.

b. Authenticity:

Your beloved diamond is exactly what you hope to adorn your life with- you don’t need to second guess it ever. 

c. Proof of Ethical Sourcing:

Certification ensures that your diamond meets the highest ethical and environmental standards. From the sourcing of materials to the actual manufacturing process- every aspect is sustainably handled with utmost care.

d. Resale Value:

A certified diamond retains greater value over time. Certification ensures that should you ever choose to upgrade or trade your diamond, it will be recognized and valued appropriately.

4. What is IGI Certification? 

 

The International Gemological Institute (IGI) is one of the most recognized certification bodies for lab-grown diamonds worldwide. With over 45 years of expertise, IGI has set the benchmark for diamond grading, ensuring that every certified stone is analyzed for cut, color, clarity, and carat weight—the 4Cs.

IGI focuses on comprehensive grading, ensuring that every stone meets strict quality benchmarks. In order to prevent frauds and fake certifications, IGI-certified diamonds have a unique identification number inscribed on the girdle—visible under magnification but completely invisible to the naked eye.

5. What is SGL Certification? 

 

SGL is a global leader in diamond grading for both natural and lab-grown diamonds. It has 23 laboratories across 5 countries. Each SGL report delivers a full 4Cs analysis (cut, color, clarity, carat), origin determination (natural vs. synthetic), detailed facet-by-facet plotting diagrams, and precise proportions grades. Its security features like Hologram, QR Code, UV/Micro Text and security paper which prevent tampering.

7. How to Spot Fake or Misleading Certifications

 

Unfortunately, as lab-grown diamonds gain popularity, fake or misleading certificates have become a growing concern. Here’s how you can protect yourself:

a. Check the Certifying Body:

Always look for the symbol of IGI. If a retailer is offering an unknown or “in-house” certificate, be cautious.

b. Verify the Certification Number:

Authentic diamonds come with a unique certification number that you can verify on the certifying body’s official website.

c. Look for Laser Inscription:

Certified diamonds have their certification number laser-inscribed on the girdle for easy verification.
