Diamond Certification

Diamond certifications, also called diamond grading reports, are essential documents that verify a diamond’s quality and authenticity. Think of them as the “report card” for your diamond. They detail key characteristics such as the 4Cs (Cut, Color, Clarity, and Carat) along with other identifying features, which are assessed by expert gemologists using advanced tools and techniques. 

At Fascinating Diamonds, every natural and lab-grown loose diamond comes with a reliable and accurate certification. Natural loose diamonds come with a GIA certificate, while lab-grown diamonds have an IGI certificate for the center stone.

Who is GIA?

The Gemological Institute of America (GIA) is the world’s most respected diamond grading authority. Founded in 1931, GIA created the 4Cs grading system and remains the gold standard for unbiased, precise evaluations. A GIA report confirms the authenticity and quality of your diamond, giving you confidence for insurance, resale, or long-term value.

What does GIA Certification covers?

• Full 4Cs grading: Cut, Clarity, Carat, Color
• Detailed proportions and characteristics
• Optional Laser Inscription for identification or personalization
• Five types of detailed grading reports are available

When will you receive the GIA certificate?

You will receive it with your product. It includes security features like a unique report number and an inscription that is on the girdle of the diamond. At Fascinating Diamonds, every loose natural diamond comes with a GIA certificate. 

Please note, accent stones are not included in this, and the certification applies only to the center stone.

The International Gemological Institute (IGI), founded in 1975, is one of the most trusted grading labs worldwide. IGI was among the first to establish strict grading guidelines for these diamonds, jewelry, gemstones, etc, ensuring they’re held to the same quality standards as natural stones. 

What does IGI cover?

• Full 4Cs grading: Cut, Clarity, Carat, Color
• Proportions, polish, and symmetry details
• Report verification online via IGI’s web-site

When will you receive the IGI Certification?

Every lab-grown diamond sold by Fascinating Diamonds includes an IGI certificate so that you can purchase with confidence.

Please note that small accent stones are not included in the certification; only the center stone is certified.

You can add an IGI certificate to your fine jewelry purchase at Fascinating Diamonds, whether it’s diamond earrings, a diamond pendant/necklace, or a diamond bracelet, at an extra cost of $150.

Once your jewelry manufacturing is completed, it is sent to IGI’s facility for certification. The jewelry-making process takes about 6–7 business days, followed by another 7-10 business days for certification. You can expect to receive both the jewelry and the IGI report within about 15 business days. 

You can get your jewelry/diamond appraised through the Gemological Appraisal Laboratory (GAL), which provides detailed reports on gemstone origin, quality, and characteristics. A GAL appraisal also includes the replacement value of your piece, which is an essential document for insurance coverage, resale, or estate planning. The cost for this service is $125 per certificate.
