How to check the laser - inscription on an igi diamond?

As a trusted supplier of IGI diamonds, I understand the importance of authenticity and quality assurance when it comes to these precious gems. One of the key ways to verify the authenticity of an IGI diamond is by checking its laser inscription. In this blog post, I'll guide you through the process of checking the laser inscription on an IGI diamond, ensuring you have the knowledge to make informed purchasing decisions.

Understanding IGI and Laser Inscriptions

The International Gemological Institute (IGI) is a world - renowned independent gemological laboratory. Their certification is highly respected in the diamond industry, providing detailed information about a diamond's characteristics, including its cut, color, clarity, and carat weight. To further guarantee the integrity of their certified diamonds, IGI uses a laser to inscribe a unique identification number on the girdle of each diamond. This inscription is a microscopic mark that serves as a permanent link between the diamond and its corresponding IGI certificate.

Tools Needed for Checking the Inscription

Before you start checking the laser inscription, you'll need a few tools. The most essential tool is a jeweler's loupe. A loupe is a magnifying glass specifically designed for gemstone inspection. A 10x loupe is a standard choice, as it provides sufficient magnification to view the inscription clearly. You can also use a microscope with higher magnification if available, which can offer a more detailed view. Additionally, good lighting is crucial. A soft, white light source, such as a desk lamp or a gemstone inspection light, will help you see the inscription more easily.

Step - by - Step Guide to Checking the Inscription

Step 1: Prepare the Diamond

First, make sure the diamond is clean. Any dirt, oil, or debris on the girdle can obscure the inscription. You can clean the diamond gently using a soft brush and mild soapy water. Rinse it thoroughly and dry it with a soft, lint - free cloth.

Step 2: Position the Diamond

Hold the diamond securely with a pair of tweezers. Place the diamond on a flat, stable surface, with the girdle facing up. The girdle is the thin band that separates the crown (the top part of the diamond) from the pavilion (the bottom part).

Step 3: Use the Loupe

Hold the loupe close to your eye and look through it. Place the loupe over the girdle of the diamond. Start by scanning the girdle slowly in a circular motion. The inscription is usually located somewhere around the girdle, and it may take a little time to find it. The inscription consists of a series of numbers and letters, which is the unique IGI identification number.

Step 4: Read the Inscription

Once you've located the inscription, try to read the numbers and letters carefully. Take your time and make sure you note down each character accurately. Compare the number on the girdle with the number on the IGI certificate. The two numbers should match exactly. If they don't match, it could indicate that the diamond is not the one described in the certificate, or there may be an issue with the authenticity of the diamond.

Comparing with the Certificate

The IGI certificate is a crucial document that provides detailed information about the diamond. It includes the diamond's 4Cs (cut, color, clarity, and carat weight), as well as the unique identification number. When you've obtained the number from the laser inscription, cross - reference it with the number on the certificate. The certificate should also have a photo of the diamond, which can be used to confirm additional details such as the diamond's shape and inclusions.

Online Verification

In addition to checking the inscription physically, IGI also offers an online verification service. You can visit the IGI official website and enter the unique identification number from the inscription. The system will then provide you with the details of the diamond, including its certification report. This online verification can be an extra layer of assurance, especially if you have any doubts about the physical inspection.

Common Issues and Troubleshooting

Sometimes, you may encounter difficulties in seeing the inscription. If the diamond has a very thin girdle, the inscription may be more difficult to find. In this case, you may need to use a higher - magnification loupe or a microscope. If the inscription is still not visible, it's possible that there is an issue with the diamond or the inscription itself. In such situations, it's advisable to consult a professional gemologist.
