Lab grown diamonds have gained popularity as ethical and sustainable alternatives to natural diamonds in the last few years. Understanding the process behind these diamonds is key to appreciating their unique qualities and benefits. This guide explores the certification process for lab-grown diamonds, offering insights into the criteria and authorities responsible for certifying these diamonds.
Why are Lab Grown Diamonds Certified?
Lab grown diamonds undergo certification through a rigorous process that provides an unbiased assessment of their characteristics and quality. This certification, often referred to as a grading report or dossier by organisations like the GIA (Gemological Institute of America) and IGI (International Gemological Institute), serve to assure purchasers that the diamond they receive matches the seller’s description.
Certifications Role Beyond Verification
It’s easy to think that certification is just about proving the diamond is real (and it does), but the role of certification goes beyond simple verification. Certification provides:
- Confidence for Buyers: You know the diamond’s attributes match the seller’s claims, from carat to clarity.
- Insurance Documentation: A certificate is a valuable document for insurance purposes, giving you an accurate evaluation should anything happen to your diamond.
- Transparency: When any retailer is buying diamonds, having these reports in hand gives them the reassurance they need. Buyer knew exactly what they were paying for—no guesswork.
How Are Lab Diamonds Graded?
Lab grown diamonds undergo the same strict grading process as natural diamonds, ensuring transparency and reliability for consumers. The grading is based on the “Four C’s” of a diamond. These criteria are assessed by certified gemologists to determine the quality and value of each diamond which include:
- Diamond Cut:This refers to the precision of the diamond’s cut and how well it reflects light. A well-cut diamond, whether natural or lab-grown, exhibits superior brilliance and sparkle due to its optimal proportions.
- Diamond Color: In diamond grading, colour refers to the absence of colour. The highest grades, such as D, E, and F, denote colourless diamonds that appear the whitest and purest. Lower grades like G to J are considered nearly colourless, displaying slight warmth.
- Diamond Clarity: Clarity assesses the presence of internal flaws or inclusions within the diamond. Diamonds with higher clarity grades (such as IF – internally flawless) are more valuable due to their rarity and lack of visible imperfections to the naked eye.
- Diamond Carat: Carat measures the weight of the diamond, which influences its size and appearance. Diamonds with similar carat weights may vary in dimensions and visual impact depending on how the weight is distributed.
Who Certifies Lab-Grown Diamonds?
Lab-grown diamond certification is done by reputable institutes such as the IGI (International Gemological Institute) and GIA (Gemological Institute of America), which are renowned globally for their expertise in diamond grading. The IGI, for instance, developed capabilities to identify and certify LGD diamonds in the early 1990s, ensuring they maintain high standards in diamond assessment.
What These Institutes Do
These institutes utilise advanced laboratories to meticulously examine both natural and lab grown diamonds, analysing microscopic and molecular differences to distinguish between them. They adhere to the established standards of the “Four C’s” (cut, colour, clarity, and carat) in their evaluations. Each diamond, whether natural or lab-grown, receives a detailed analysis report that includes its origin and scores on the Four C’s.
Why Lab-Grown Diamonds Are an Exciting Option
This certification process ensures transparency and authenticity, providing jewellers and consumers with assurance regarding the quality and characteristics of lab-grown diamonds through a diamond certificate of authenticity.
Understanding the lab grown diamond certification process provides insight into the innovation and technology behind creating these ethically sourced gems.
