Diamond Certification
AAVAL Jewelry is delighted to offer our clients clear guarantees via lab-grown diamond certifications. These certifications, which are supported by respected independent labs like the GIA, IGI, SGL, and AAVAL Authentic Certificate, function as physical and digital
documents that describe the remarkable qualities of our diamonds and guarantee that every transaction satisfies the greatest requirements for originality and grade.
What is a certified diamond?
A diamond that has passed an in-depth independent evaluation by a reputable gemological laboratory is certified. A diamond certification, a document that offers a
detailed study of the diamond’s qualities, is the result of this evaluation. Details like the diamond’s 4Cs—cut, colour, clarity, carat weight—and other pertinent data are included in the certification.
The Gemological Institute of America (GIA), the International Gemological Institute (IGI), and other respectable gemological laboratories have created industry-standard standards that are generally used to grade certified diamonds. These accreditations are
useful resources for both buyers and sellers in the diamond business, providing a trustworthy and objective evaluation of a diamond’s quality.
What is IGI?
IGI certification refers to a quality assessment issued by the International Gemological
Institute (IGI) for diamonds, gemstones, and jewellery. Here’s a breakdown of what it
means:
● Internationally Recognized: IGI is one of the world’s largest and most
respected gemological laboratories. Their certifications are recognized by many
jewellery retailers and insurance companies around the globe.
● Evaluation Process: An IGI certification involves a thorough examination of a
gemstone or piece of jewellery using sophisticated equipment and techniques.
Gemologists assess various aspects, including:
○ Diamonds: cut, clarity, colour, and carat weight.
○ Gemstones: species, variety, treatments, and any enhancements.
○ Jewellery: metal type, craftsmanship, and overall quality.
● Certification Report: After evaluation, IGI issues a detailed report that outlines
the diamond’s or gemstone’s characteristics. It also includes information about
any treatments or enhancements that may have been applied.
What is GIA?
The Gemological Institute of America, the world’s leading authority on diamonds and gemstones, issues GIA certification, which is also occasionally referred to as a GIA diamond report. It denotes that a diamond has been subjected to an exacting and independent analysis to evaluate its quality according to the following standards:
The 4Cs of Diamonds: The Cut, Clarity, Color, and Carat Weight (4Cs) system of diamond grading was developed by the GIA and is currently widely used. These qualities are carefully assessed for every diamond, and the GIA report gives a grade based on the results.
Cut Grade: A diamond’s cut is said to have the greatest impact on its fire and brilliance. To guarantee ideal light performance, GIA evaluates cut quality using a very strict and precise system.
Clarity Grade: The diamond’s ability to show internal or external flaws is indicated by this grade. The GIA uses a comprehensive clarity grading scale that makes it possible to precisely understand the flaws in the diamond.
Colour Grade: A diamond’s colour is rated by the GIA on a scale from D (colourless) to Z (light yellow). Colorless diamonds are usually thought to be the most valuable.
Carat Weight: Using calibrated technology, the precise weight of the diamond is determined and recorded on the GIA report.
What is EGL?
EGL certification refers to a diamond grading report issued by the European Gemological Laboratories (EGL), a network of independent gemological laboratories with locations around the world. This is an outline of what it includes:
Grading Procedure: EGL employs a uniform method, similar to GIA and IGI, to evaluate diamonds according to the 4Cs: cut, clarity, colour, and carat weight. Each diamond is examined by qualified gemologists, who then grade it accordingly on the EGL certificate.
Reputation: Although EGL is a reputable gemological institute, it’s vital to remember that people tend to view its grading guidelines as being less stringent than those of GIA. This implies that a diamond certified by EGL may obtain a higher clarity or colour grade than a diamond certified by GIA for the same stone.
What is SGL?
An SGL certificate refers to a diamond grading report issued by SGL Labs, an international diamond certification and grading laboratory network. Here’s what you need to know about SGL certification:
Established Lab: SGL Labs is an American-British business with a burgeoning global footprint. They are a major player in the diamond certification market, with a network of laboratories spread across multiple nations.
Grading Procedure: SGL Labs, like other significant gemological institutions, grades diamonds according to the 4Cs: cut, clarity, colour, and carat weight—using a uniform approach. Skilled gemologists carefully evaluate every diamond, grading it accordingly and recording the results on the SGL certificate.
Reputation: SGL Labs is a trustworthy company, however, it’s crucial to take into account where they stand in the industry:
International Recognition: SGL certifications are accepted all around the world, however, they might not be as respected as those issued by the GIA, the industry’s premier body.
