IGL diamond certification serves several crucial purposes in the diamond industry. Its primary objective is to provide consumers with an unbiased and professional evaluation of a diamond’s quality and characteristics. By certifying diamonds, IGL aims to ensure transparency and build trust between buyers and sellers. It helps consumers make informed decisions by providing them with reliable information about the diamond they are purchasing. Additionally, IGL certification serves as a legal document that can be used for insurance purposes, resale, or appraisal.

Process of IGL Diamond Certification

The process of IGL diamond certification involves a series of rigorous assessments and evaluations performed by trained gemologists. Let’s take a closer look at the step-by-step process:

Step 1: Diamond Submission

The certification process begins with the submission of a diamond to an IGL laboratory. This can be done by either the diamond owner or a retailer. The diamond is securely packaged and sent to the laboratory for evaluation.

Step 2: Initial Examination

Once the diamond reaches the laboratory, it undergoes an initial examination to determine its authenticity and whether it meets the basic requirements for certification. The gemologists check for any visible flaws or treatments that may affect the diamond’s quality.

Step 3: Grading the 4Cs

The gemologists then proceed to evaluate the diamond based on the four key criteria known as the 4Cs – carat weight, cut, color, and clarity. Each of these factors plays a significant role in determining the overall quality and value of a diamond.

Carat Weight:

The carat weight refers to the size or mass of a diamond. It is measured in metric carats, where one carat is equivalent to 200 milligrams. The gemologists use precise weighing scales to determine the carat weight of the diamond. The weight is then recorded in the certification report.

Cut:

The cut of a diamond refers to how well it has been shaped and faceted. It directly impacts the diamond’s brilliance and sparkle. The gemologists assess the proportions, symmetry, and polish of the diamond to determine its cut grade. The cut grade ranges from Excellent to Poor, with Excellent being the highest grade indicating exceptional brilliance and fire.

Color:

The color of a diamond refers to its hue, ranging from colorless to light yellow or brown. The gemologists compare the diamond to a set of master stones to determine its color grade. The color grades range from D (colorless) to Z (light yellow or brown). Diamonds in the D-F range are considered colorless, while those in the G-J range are near colorless.

Clarity:

The clarity of a diamond refers to the presence of internal and external flaws, known as inclusions and blemishes, respectively. The gemologists use 10x magnification to examine the diamond and assign it a clarity grade. The clarity grades range from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye).

Step 4: Additional Factors

In addition to the 4Cs, IGL also evaluates additional factors that can impact a diamond’s value and desirability. These include fluorescence and symmetry.

Fluorescence:

Fluorescence refers to a diamond’s reaction to ultraviolet light. Some diamonds emit a visible glow when exposed to UV light. The gemologists assess the intensity of fluorescence and record it in the certification report. Fluorescence can have both positive and negative effects on a diamond’s appearance, depending on personal preference.

Symmetry:

Symmetry refers to how well the facets of a diamond align and interact with each other. The gemologists evaluate the diamond’s symmetry by assessing the precision of its shape and faceting. A higher symmetry grade indicates better alignment and overall aesthetics.

Step 5: Certification Report

Based on the assessments and evaluations, the gemologists prepare a detailed certification report. This report contains all the essential information about the diamond, including its 4Cs, additional factors, measurements, and any relevant comments or observations. The certification report is then securely issued by IGL, providing a permanent record of the diamond’s characteristics.

Significance of IGL Diamond Certification

IGL diamond certification holds immense significance in the diamond industry due to the following reasons:

Authenticity and Quality Assurance

One of the primary advantages of purchasing certified diamonds is the assurance of authenticity and quality. IGL certification guarantees that the diamond is natural and has not undergone any treatments or enhancements that may alter its appearance or value. It provides buyers with peace of mind, knowing that they are investing in a genuine and high-quality diamond.

Objective Evaluation

IGL certification ensures an objective evaluation of a diamond’s characteristics. As an independent laboratory, IGL does not have any vested interest in the sale of diamonds. This eliminates biases and conflicts of interest that may arise if the assessment were conducted by the seller. Consumers can trust the accuracy and impartiality of IGL’s evaluations.

Transparency and Trust

By certifying diamonds, IGL promotes transparency and builds trust between buyers and sellers. The certification report provides comprehensive information about the diamond, allowing buyers to make informed decisions. It eliminates the need for relying solely on the seller’s claims and descriptions. With IGL certification, consumers can have confidence in the accuracy and integrity of the information provided.

Insurance and Appraisal

An IGL certification report serves as a legal document that can be used for insurance purposes or when seeking an appraisal. The detailed information provided in the report helps insurers determine the value of the diamond accurately. Additionally, it simplifies the process of reselling or upgrading the diamond in the future, as potential buyers can trust the authenticity and quality stated in the certification report.

Misconceptions and Criticisms of IGL Diamond Certification

Like any other certification laboratory, IGL has faced some misconceptions and criticisms over the years. It is essential to address these concerns and provide a balanced perspective:

Subjectivity in Assessments

One common criticism of IGL certification is the perceived subjectivity in assessing certain factors such as cut and color. While gemologists follow specific guidelines and standards, there may be slight variations in their evaluations. It is important to note that these variations exist across different laboratories, and the differences are often minimal. However, IGL continuously strives to maintain consistency and accuracy in its assessments through ongoing training and calibration.

Lower Market Recognition

Compared to some other well-known diamond certification laboratories, IGL may have relatively lower market recognition. This can lead to concerns about the credibility and acceptance of IGL-certified diamonds. However, it is crucial to understand that market recognition does not necessarily reflect the accuracy or quality of the certifications. IGL has been in operation for several years and has established a reputable presence in the diamond industry. Its certifications are widely accepted by retailers, wholesalers, and consumers alike.

Perceived Leniency in Grading

There have been occasional claims that IGL may be more lenient in its grading compared to some other laboratories. This perception arises from the potential differences in grading standards and criteria used by different laboratories. It is important to remember that grading is not an exact science, and there can be variations in assessments across laboratories. However, IGL adheres to internationally recognized grading standards and continuously works towards maintaining consistency and accuracy in its evaluations.
