The world's first Dlasercode history

It is based on the theory that no two gemstones are exactly alike, and therefore, the internal mass light of each gemstone will be unique. The system records the subtle differences in the cut pattern of a diamond. It acts like a fingerprint to identify a person. It can generate an aurora generated by a vertical laser beam that produces a diamond "reflection pattern" created by a collinated beam of light directed at the gem's countertop. Although the two stones may look similar, the GIL shadow is difficult enough to identify each diamond, and the world's first GIL was recorded and registered on March 12, 1976.

A milestone in diamond anti-counterfeiting technology

Despite the complexity of diamond identification, tens of millions of dollars worth of lost and stolen diamonds have been identified and returned to their rightful owners, and more than $10 billion worth of diamonds have been marked with a GIL. Including Rare Diamonds and Rare GIL Gemstones from the largest museum in the United States. Headquartered in New York City, New York, the world's only non-invasive identification system. GIL's technology is now used by diamond cutters, gemstone laboratories, wholesalers, manufacturers, retailers and e-commerce networks worldwide. Recorded and registered on March 12, 1976 GL debuted in the United States in 1978 and is headquartered in Chicago. GIL was quickly accepted as irrefutable evidence in court, securing convictions, and remains the world's only scientific, non-invasive method of diamond identification.

The more stringent 6EX standard for gemstone identification

In terms of the traditional 4C grading of diamonds, GIL maintains the same strict and internationally recognized US standards as GIA. In addition to the traditional 4C, GIL creatively introduced the optical evaluation of diamonds in the process of continuous improvement of the grading system. To evaluate diamond cutting standards in a more comprehensive and systematic way from three projects, namely light return, optical symmetry and scintillation. With the traditional cut/polish/symmetry, the total is 6EX!! From the most professional and authoritative point of view, we will identify the best diamond for you.
