FOCUS 焦点 JNA July/August 2025 | 11 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.” According to Nyfeler, Gübelin Gem Lab’s main development project this year is getting Gemtelligence ready for external use. Third parties such as other gem labs or large brands that operate their own labs will be able to use Gemtelligence to interpret data they collect on their stones in their premises. “We are already speaking to some select laboratories that are keen to partner with us on this. Towards the end of this year, the technology to grant externals access to Gemtelligence should be ready, and third parties can start profiting from the knowledge and expertise contained in the system,” he disclosed. Companies using the Gemtelligence service can decide whether to disclose their partnership with Gübelin Gem Lab, Nyfeler added. 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 more than 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 have started to apply the nano-tracers from Provenance Proof on melée diamonds and jewellery this year, making true, verifiable supply chain transparency a more standard feature of jewellery,” said Nyfeler. KGK Suisse SA launched the first DNA-tagged melee diamonds in May. These diamonds are fully verifiable on the blockchain and come with Provenance Proof certificates of origin. Diamond traceability is indeed gaining momentum in a market seeking greater transparency, with more enterprises adding tracking functionalities to their stones. In June, Botswana-based rough diamond marketing company, the Okavango Diamond Company (ODC) joined Tracr, the industry-wide diamond blockchain programme developed by De Beers Group. Wholly owned by the government of Botswana, ODC began registering its rough diamonds in the 3 gram-to-6 gram and 2-carat to 10-carat sizes on Tracr, increasing the availability of traceable diamonds from the country. Operational ease In the midstream, ingenious breakthroughs are poised to deliver significant benefits. Case in point is the Certified Hybrid Diamond Master Set, which is proving a game changer for colour grading.
