珠宝业设备及用品供应商名录 2026 | 11 市场情报 KGK Suisse SA launched the first DNA-tagged melee diamonds in May 2025. These diamonds are fully verifiable on the blockchain and come with Provenance Proof certificates of origin. Jewellery narratives Transparency and traceability extend to finished jewellery as well, offering end-to-end supply chain visibility. Experloop is the world’s first gold microchip for the certification and identification of jewellery and watches. Developed by Singapore jeweller Michael Koh, the 2mm round gold RFID microchip is attached to watches and jewellery and can be scanned to retrieve relevant data on the piece’s legacy and story. The item’s owner can access and update their data directly through the Experloop software system. According to Koh, his main objective is to allow the jewellery piece “to tell its own story.” Since jewellery is often passed down to the next Together with the Gübelin Academy, the lab also acquired a collection of more than 1,800 reference samples from its former head of Research, Dietmar Schwarz. After careful analysis and scrutiny, this was likewise included in the training data. Significant gains While the most immediate impact of Gemtelligence is greater consistency of results in lab reports, the system also manages to retrieve more information from less data, according to Gübelin Gem Lab Managing Director Daniel Nyfeler. “In some cases, this allows us to shorten the testing protocol. For some stones, we can forgo certain time-consuming microscopic description and/or the expensive chemical analysis by Laser Ablation ICPMS,” he noted. These efficiency gains and cost savings prompted Gübelin Gem Lab to offer the streamlined Gem Passport service and even open a location in Bangkok. At CHF 200 (around US$243), the Gem Passport provides country of origin and heat treatment determination for rubies, blue sapphires and emeralds of up to 3 carats. “Owing to the significantly lower cost and the swift turnaround times for Gem Passport, many clients now consider using Gübelin Gem Lab for gemstones of commercial quality,” Nyfeler disclosed. “Also, many of the bigger brands, which buy large volumes of smaller stones, have started to use Gem Passports for stones whose value would not justify the cost of a standard Gübelin Gem Lab Report.” At press time, Gübelin Gem Lab was readying Gemtelligence for external use, with the technology needed to grant access to third parties scheduled for completion by the end of 2025. This would enable other gemmological labs and large brands that operate their own labs to use Gemtelligence to interpret data they collect on their stones in their premises. According to Nyfeler, these companies can decide whether to disclose their partnership with Gübelin Gem Lab. Traceability for gems It was also Gübelin Gem Lab that first introduced traceability for coloured gemstones with the official launch of the Emerald Paternity Test in 2017 followed by the Provenance Proof Initiative to track the origin and journey of gemstones. Today, the latter leads tracking and tracing technologies in the coloured gemstone industry with over 40 million gems on the Provenance Proof Blockchain and a community of over 700 companies. Provenance Proof, which spun off from Gübelin Gem Lab in 2020, now also encompasses diamonds and jewellery. “Major diamond manufacturers and jewellery brands started to apply the nano-tracers from Provenance Proof on melee diamonds and jewellery in 2025, making true, verifiable supply chain transparency a more standard feature of jewellery,” said Nyfeler.
