How to use diamond laser coding to ensure purchase safety?

When buying a diamond or engagement ring , it is vital to ensure that the diamond you are purchasing is authentic and of the quality you desire. For buyers who are not familiar with diamonds, identifying the identity of each individual diamond can be a challenge. At this time, diamond certificates and laser codes become your important protection tools. ANTONELLI explains how certificates and laser codes can help you buy natural or cultured diamonds with confidence.

What is Diamond Laser Coding?

Diamond laser coding is a unique tiny number, usually engraved on the girdle of the diamond. This code corresponds to the diamond’s certificate number. You only need to use a high-power magnifying glass or microscope to check whether the code on the diamond is consistent with the certificate. This not only helps confirm the identity of the diamond, but also adds transparency to the transaction.

For example, both natural diamonds and laboratory-grown diamonds can be accompanied by a certificate issued by GIA or IGI, and the Inscription(s) column on the certificate will clearly indicate the laser code.

The Importance of Diamond Certificates

A diamond certificate is a key document to identify the quality and authenticity of a diamond. Here is why it matters:

• Quality assurance: The certificate lists in detail the diamond’s 4Cs (carat weight, color, cut and clarity) and other information to help buyers choose diamonds that meet their needs.
• Certificate of Authenticity: A certificate from a recognized organization such as GIA or IGI ensures that the diamond you are buying is real and not man-made.
• Value-added information: The certificate can help you understand the origin of the diamond, increasing its value upon future resale.
• Insurance Basis: The certificate can be used as the valuation basis for diamond insurance, providing more comprehensive protection.

The importance of checking laser codes

Checking the laser code is the best way to ensure that the diamond you purchase is exactly as described on the certificate. The following are several major functions of laser coding:

• Individual Identification: Each diamond is laser-coded to be unique, helping to ensure its identity.
• Confirm the match: Checking the laser code upon delivery will immediately confirm that the diamond you received is the same as the one you purchased.
• Prevent confusion: During the diamond cleaning or setting process, laser coding can effectively prevent your diamond from being confused with others.
• Increased transparency: Laser coding allows buyers and sellers to conduct transactions with greater confidence.

How to check the diamond laser code?

When you purchase or deliver a diamond, be sure to check the laser code on the diamond's girdle and compare it with the number on the certificate. This ensures that the diamond you purchase is exactly the one you purchased. If you have any questions about how to check, you can ask ANTONELLI's professional team to assist you to ensure your purchase process is smooth and worry-free.
