This article introduces a new certification standard, “Eternal Light,” developed by JD.com and IGI to quantify a diamond’s brilliance—a key quality traditionally difficult for consumers to assess. The initiative aims to bring greater transparency and data-driven insight to diamond selection.

For a long time, ordinary consumers have been able to intuitively judge dimensions such as carat weight and cut when selecting diamonds, but it has not been easy to assess a diamond’s brilliance. To address this, JD.com’s Jewelry division has officially partnered with the International Gemological Institute (IGI) to launch the “Eternal Light” Light Performance Certification Report. This initiative uses professional data to help consumers select natural diamonds with outstanding brilliance.
Simultaneously, JD.com has collaborated with diamond brands such as Xizuan, De Beers Forevermark, and Diamond World to launch limited sales of diamonds that meet this light performance certification, accompanied by a 92% discount offer. From February 7th to February 14th, consumers can open the JD.com APP and search for “Natural Diamond Eternal Light” to make their selections, ensuring every token of affection is brilliant with evidence and making gift-giving more meaningful.

The selection of natural diamonds has long relied on the traditional “4C standards”—Carat, Color, Clarity, and Cut. However, for ordinary consumers, it is difficult to intuitively judge from these dimensions alone whether a diamond is truly “bright” or “brilliant.” In response to this situation, JD.com partnered with IGI ahead of the Valentine’s Day season to add the “Eternal Light” Light Performance Certification to the 4C standards for natural round diamonds.

As a globally renowned independent gemstone首 tier鉴定 institution, IGI has always promoted transparency and standardization in the diamond industry with rigorous scientific standards. Prior to this collaboration, JD.com has long been deeply engaged in the diamond field, continuously推出多项 measures to助力 the diamond industry’s quality improvement and standardized development.
In the future, JD.com will continue to deepen its relevant cooperation with IGI, using technology to empower quality and using quality to safeguard trust. The company plans to gradually expand the coverage of the “Eternal Light” Light Performance Certification and collaborate with more优质 gemstone brands to bring consumers natural diamonds that balance quality and value for money. Open the JD.com APP and search for “Natural Diamond Eternal Light” to purchase brilliantly certified diamonds and instantly create your专属 Valentine’s Day专属 memory.
