This cutting-edge innovation, which embeds Radio Frequency Identification (RFID) tags into bead nuclei, allows for greater transparency throughout the pearl supply chain.
In a breakthrough for the jewellery industry, GIA will now include RFID reference numbers in their Cultured Pearl Reports for pearls containing bead nuclei with these embedded RFID chips. This unique identifier enhances the traceability of each pearl, making it easier to track its origin and movement from the farm to the market.
Fukui Shell Nucleus Factory recently submitted a batch of bead-cultured akoya, South Sea, and Tahitian pearls to GIA, all embedded with RFID chips using their patented pearl authentication technology. After a decade of development, the factory is rolling out this innovation to pearl producers in major regions such as French Polynesia, Myanmar, Indonesia, Japan, and China.
“With sustainability becoming more important to consumers, this technology plays a vital role in telling the complete story of these gems,” said Tom Moses, GIA’s Executive Vice President and Chief Laboratory and Research Officer. “Integrating RFID details into GIA Cultured Pearl Reports represents a significant leap forward in traceability and transparency within the pearl industry.”
The technology, known as Metakaku, embeds a wireless RFID tag into the pearl’s nucleus, enabling it to be tracked throughout its lifecycle. During GIA’s examination, the RFID reference number is detected and added to the report, allowing each pearl to be uniquely identified based on its quality attributes, as defined by GIA’s 7 Pearl Value Factors™ — Size, Shape, Color, Nacre, Luster, Surface, and Matching.
While traceability in the pearl industry remains a complex challenge, especially for sustainably cultured pearls, this technology provides a promising solution. A pearl that can be traced back to its source not only enhances consumer confidence but also tells a powerful story of its journey from oyster to ornament.
“Stories have the power to connect people with pearls in deeper, more meaningful ways,” said David Wong, the innovator behind Metakaku. “Through this technology, we aim to provide value and new perspectives, encouraging exploration and inspiring greater opportunities for every pearl harvested.”
GIA has been at the forefront of pearl identification and classification since 1949. Its role in shaping industry standards, including revising the U.S. Federal Trade Commission’s pearl guidelines, has positioned it as a global leader in the development of transparent and reliable pearl descriptions.
This new traceability initiative marks an exciting new chapter for GIA and the pearl industry, as sustainability and transparency become increasingly vital to consumers around the world.
